Lower rear fender repairs
These areas were rusted out, non-existent.
After installing the outer sills, I left these voids until I was further along into the fenders. Now was the time.
Left and right side, before and after:
With the 1/4" rod firmly in place representing the fender lips, I formed a few fender shapes in cardboard to see what I liked and would work with tire clearance.
Shaped 1/8" rod:
Cardboard taped in place:
After finalizing the end shape, I decided to go with four small panels in the middle and two larger ones at either end. The five 1/8" rods would mark the butt weld lines with the end panels lap welded to the body.
Final trim and body prep:

Now it was time to just fill in the blanks. I recorded the length and shape of each 1/8" dividing rod to carry over to the left side. The paper cut outs confirmed the panel sizes side to side:

Rear panel installed:
Center panels going in:

Left side done:
Several different panels on each side were needed to join what was left of the old inner panels to the new fender. It may have been easier to complete this when the body goes on the rotisserie but I wanted to get it out of the way.
Panels cut and installed:
The doors on this car were in tough shape. After I removed the door skins, (heavy with filler and rust) I sent the inner doors, (shells) out to be acid dipped. This removes all the rust. Not much came back.
The structure of an automotive door is quite standard in the industry. You have a shell which the hinge is mounted to and it has flanges which the edges of the door skin is folded over on.
These door shells would need new hinge mount assemblies and flanges replaced where needed.

Typical flange destruction, top front corner:

Repairing the door shell flanges entailed estimating what was there originally and what the new door skin would require. I fabricated angle sections and with a liberal use of the shrinker/stretcher, plug welded them to the shell.

After hanging the repaired door shells, I decided to install the Spal power window kit now before the door skins go on.
The kit I choose basically is a motor driven cable loop that drives your original window regulator. Mount the motor where ever you can.

Interior door handle and lock
Changing the interior door lock to a late model style required fabricating a mounting assembly attached to the door shell that could be adjusted in or out according to the door panel that I end up with.
That was pretty straight forward, but the original handle used a push motion to lock the door. To get this motion, I added a push/pull rod on top of the door shell and fabricated a lever assembly to operate the lock trigger.

Outside Door Handle
When I got the car, the outside door handle would open the door but there was no key and the locking function was not working.
Whilst investigating, I discovered the "barrel cup casting" on both sides had the top portion broken off.
Using 20 ga. sheet metal, I fabricated one left, one right, re-keyed the tumblers to my TR6 key I had and put it all together.

Chuck from Monocoque Metal Works says E-type doors are the bane of his existence. Fitting them to the body shell and getting the gaps correct can be quite a challenge.
When it came time to installing my after market door skins on my repaired door shells, I could see something wasn't correct on the right side. After conducting a survey of the two, I found the one skin had the crease line stamped 1/4" lower than the other. My supplier in the States graciously offered to do an exchange, but considering shipping costs, I elected to hammer form a higher crease line to match the shell and the other skin.

Setting Door Gaps
Apparently, when these cars were made in England, as the car body went down the assembly line, they would have a row of completed doors available, and would choose one that best fit the car in front of them. After mounting the door, they would lead in the body to fit the door.
Well, not in my case. Here it was a matter mostly of making the door fit the opening and doing some modifications to the body shell where needed.
With a good reliable door hinge, I was looking for a 1/8" to 3/16" door gap. With the doors mounted, there was very little length where I needed it. Adding or removing metal would fix it.
The left side bulkhead between the bonnet and the door was sitting proud of the door by more than 1/8". This could have been compensated for by adding filler to the door but that is never a good option. I opted to cut and section that area to bring it in line.
- first, remove the factory lead in the seam.
- second, cut and slice
- third, weld back together
- fourth, grind weld
The upper front section of the E-type door has never appealed to me. The weather seal often doesn't sit right and a crisp, clean door gap is seldom achieved. I'm taking a chance on improving this.
- photo of red car shows weather seal mismatch
- set 1/8" rod in place
- weld rod to body
- finished door gap to 1/8"
The gap at the bottom of both doors was too small. I took it to 1/8" by cutting back a 2" length, welding and grinding then moving ahead another 2". My pace ended up at 6"/ hour.
Example of one 2" length:

Door Window Frame
Fitting the window frame into the door shell is a matter of making it fit the best you can in the space you’re given. Much like getting the door shell to work with the hinges and latch mechanism, the door frame must work with what it comes in contact with. A lot of variance of fit can be taken up with the door seal that this car comes with, except for one area and that is the contact between the rear edge of the window frame to the ¼ window or rear side glass window. This is a double seal that requires a gap tolerance of 1/16”.
Keeping these two windows in that relationship really limits how much you can move things around.
The ¼ window attaches to a B post that mounts with a limited amount of adjustability, top and bottom.
Using the rebuilt door shells and new door skins, I set about to try and make the window frame fit in the space with the correct gap to the ¼ window. It took a lot of study but I came to the conclusion that the mounting screws for the B post were never installed correctly from the factory to allow for a correct gap. This is especially critical since with the window being 24” long, a small angle changes the window position a lot. I knocked out the captive nuts and enlarged the two holes enough to move the B post to where I needed it. If it never fit properly before, it’s going to fit properly now.

Back to the Bonnet
Having taken care of two major areas of concern, the rear fenders and the doors, I returned to the bonnet. As previously documented, all the metal work repairs have been done, it's hinged and sitting well. But it's far from complete.
On the job list are covered headlight lenses. Out of curiosity, I spoke to the previous owner about the fact that the right fender had the Series I flanges to mount the lens yet the left fender and center section was straight cut metal, as if open headlights had been installed. He knew nothing of all that. Odd arrangement.
So starting from scratch, I needed to keep to a similar plan form to original for the lens and make both sides the same, mirror image. I got one chrome headlight trim ring with the car so from that and sizing up the opening that was there, both sides, I came up with a CAD piece to represent the flange I needed to fabricate.
My plan was to bend 3/16" rod to the shape needed then weld it to the opening edge. I would add a sheet metal flange, stepped down after that, to match a formed acrylic custom formed lens.
-CAD piece in place to trim metal
-3/16" rod bent and in place
-rod split at fender/center section
Welded in place:
With all the metal work completed on the four bonnet panels, I was looking forward to finally getting it assembled. After a good cleaning, I sent it out to be epoxy primed.
I was willing to add a reasonable amount of filler where the panels join in order to get a smooth transition from one to the other. In order achieve this and still be able to separate the panels, I slipped thin sheets of aluminum between them. The flange surfaces were finishes as well.
I also took this opportunity to final shape the lower valance. This would be very difficult to do while it’s on the car and flipping the bonnet on its back is cumbersome.
All the flanges were epoxy primed again before final assembly.
I had to reconfigure my bonnet lift now that it was in one piece.

-epoxy prime all mating surfaces

Bonnet Splash Panels
With the bonnet assembled and on the car, I could now proceed with fabricating the inner splash panels. These needed to line up with the lower splash panels already mounted to the chassis. The 1/16” aluminum panels would be mounted to 20 gauge angle brackets attached to the bonnet underside with adhesive.
First step was to project up from the chassis panels and create a layout on the underside of the bonnet representing the placement of the bonnet panels. Along these lines, I cut cardboard, shaped to the bonnet and lining up with the chassis panels.
With these cardboard templates, I fabricated ¾” wide angle brackets with compound curves to match the shape of the bonnet. The compound curve required me to slice the one side of the angle and bend it inwards.
After test fitting the brackets to the bonnet, I fastened them to the panels temporarily then applied adhesive to the bonnet side of the bracket and secured it to the bonnet. Any discrepancies of fit would be taken up by the adhesive.
Originally, Jaguar fastened this type of bracket to the bonnet with a Sikaflex product. With some research within the Jaguar owner’s community, I ended up using a 3M product, Marine Adhesive Sealant 5200.
With brackets attached, I drilled through the bracket/panel and used 3/16” blind rivets to assemble everything.

Vintage kitchen flour/sugar scoops looked remarkably like the sugar scoops Jaguar used to fill the space in the bonnet ahead of the headlights. It’s obvious how this item acquired its name.
The bonnet I started with only had one scruffy scoop which was of little use to pattern off of so I would be starting from scratch. Aluminum was my choice of material.
The basic design structure would be the curved scoop welded to a flat panel, bolted to the flanges on the inside of the bonnet. This flat panel would have a cut out to accept the headlight that would be mounted on its own flat panel. This would enable me to remove the headlight for servicing without disturbing the sugar scoop assembly.

Headlight Lens Covers
To fabricate my own lens covers, I’d first have to make a mold to form them off of.
My plan was to make the base of the mold from polystyrene rigid foam board then finish it with painted bondo.
I started with a stepped piece of foam, supported from the back and shaped it to the headlight opening.
(click anywhere on collage photo to blow it up to full size - in a new window)
-foam spaced inward
It was essential to support the mold from the back side to set it inward to allow for the bondo thickness. I started with the green fiberglass filler and finished with regular filler.
-finished to meet metal headlight opening
Several layers to the mold:

Forming Lens Covers
With some extensive research, I choose 3mm PETG as my material to form the lens covers from. I built a vacuum former, plans copied from others on the internet. It turned out to be very effective in shaping to the mold but I got way too much “mark off”, imperfections from the painted mold, on the lens. I covered the mold with flannel but still had the imperfections.
After a phone call to a shop in California that fabricates canopies for aircraft, they suggested I try a drape form method instead of vacuum form. With some experimentation, I found a reduced time in the oven and concentrated pressure on the perimeter of the mold gave me a good shape and clarity.
In the end, a closely shaped blank, heated, dropped over the mold then pressed down with a perimeter press, worked. Using about 2 minutes in a 300 degree oven, was good.

Lens cover flanges
Happy with the shape of the lens cover, I needed something to mount them to. At this point, all I had was an opening lined with 3/16” steel rod.
I started by setting the lens in the opening, flush with the outer surface of the bonnet. From the inside, I tacked strips of 20 ga. metal where the 6 mounting screws would go. The trick was allowing for the 1/8” gasket and getting the angle correct to match the lens.
After the 6 sections were in place, I just filled in the blanks, metal finished it, then drilled and welded 6/32” nuts on the back side.

-mount sections marked and tacked
-welded, mostly from back side
Filling in the voids:
Finishing Lens Cover
Final trimming of the lens was done with a jig saw and a disc sander.
To finish the lens, I painted the outside perimeter black on the inside. The fastening screws I choose were rather specific, described here:
“#6-32 Phillips Flat Head Machine Screws in Black Oxide 18-8 Stainless Steel featuring a 100-degree countersunk head are often used for shorter length fasteners to allow for a greater threaded length. 100-degree taper screws are often used when fastening thinner materials.”
I cut gaskets from 1/8” neoprene and used contact cement, one side only, to glue it to the black painted side.
A small stack of heavier rubber rings went under the screws to allow more fastening pressure without distorting the lens shape.
The screw head counter sank successfully using a ¼” twist drill bit.
-marked and painted
-rubber spacers under screws

Front Signal Light
After seeing someone else using Jaguar XK8 front signal lights in their modified E-type, I asked permission if I could do the same. Permission granted.
After purchasing the assemblies, I found the curvature wasn’t correct. Also, I wanted clear lenses as opposed to the orange ones supplied.
The first thing I did was establish the shape I needed, then gently heat the clear lens and coax it into place.
Changing the lamp body required some slicing and dicing, adding material with epoxy.
A sheet metal frame work was set in the fender to mount the lens body and finished with fiberglass filler.

-reshaping after market lens
-slicing lens body
-reshaped lens body before epoxy

Wiper Assembly Test
The original wiper motor that I got with the car came untested of course. I was relieved to find the motor ran well. In order to incorporate the GM wiper switch that mounts on the tilt steering column, I had to add two relays.
Interestingly enough, the self park switch is mounted on the center wiper arm. It has a remote adjuster that extends below to fine tune the park position.

Steering rack limiters
Steering rack limiters provide an adjustable range of steering motion and eliminate any tire rubbing problems. I needed to keep the tires off the inner fenders so I fabricated some “doughnuts” to install inside of the inner tie rod ends and the rack casing.

Also added some drilled 5/8” nuts tacked to the tie rod to make toe adjustments easier:
Thanks for looking.
