This car was hit on this side and the repair was pitiful. I replaced the rocker panel and the A pillar (not pictured yet) much better

Most of the tin work is done. I have to do some rust repair in a few spots
P1010759.JPG
I got the gas and brake pedal made and mounted. steering column is mounted at the firewall
but I need to fab up a mount for the front of it

Repaired all the rust on the drivers side
P1010764.JPG

Just one more little patch and the passenger side will be done
P1010772.JPG
All patched up
P1010768.JPG

P1010773.JPG
Test fitting the dash components. I still have to fab up a steering column mount and needed everything in there so it doesn't interfere with any thing. I'm still going to put a wooden dash over every thing with indivdual gauge cut outs so it won't look like there's an instrument cluster in there.
P1010775.JPG
I know your probably scratching your head wondering what is going on in this pic. I'm a paraplegic and this car will be driven with hand controls so I wanted the pedals to swing up and out of my way. They can be swung down incase some one else needs to drive it.

I didn't really want to have a roll bar / cage but being a paraplegic I needed some thing over my head to grab onto so I can get in and out. Since I had to make it I tried to make it as structural as possible, it's welded to the body and bolted to the chassis. The top still goes up and down. It still needs 2 more bars from the top of the main hoop down to the chassis.

I always hated the TR6 tail lights and that huge license plate cutout.
P1010869.JPG
Finished up the rest of the roll bar / cage. All mounting points are bolted to the chassis
P1010868.JPG
P1010870.JPG
This is where the exhaust will exit. I haven't decided how I'm going to finish them off yet.

Fitting the body panels
P1010903.JPG
P1010906.JPG
P1010907.JPG
Set the front fenders and nose piece on. I have to fab up a tilting structure for the front end and make everything fit. I'm going to need a hood before I proceed. Seeing how I can't find a fiberglass one any where I decided to make one
P1010911.jpg
P1010913.jpg
This is the plug I made to form the mold.
P1010915.jpg
The mold is done and turned out pretty good. This was way more time consuming then planned. It was also a major pain in the a$$. This being my first large scale fiberglass project, I'm happy with the results and I learned a lot about fiberglassing. Now to actually make the hood
hood cropped.jpg
The hood turned out pretty good. The X you see is the reinforcing ribs I made underneath.The black marks are were I marked the mat to rip it to size. I didn't use any gel coat because 1) it's expensive, 2) I haven't decided if there is going to be a scoop or heat extractor or whatever on top and I'd have to grind or cut most of it away anyway
P1010918.JPG
Set the hood on. Now that I have all the body pieces I can start on the the tilting frame and alignment of the body panels
P1010932.JPG
Well I've been using wizzer wheels all my life and heard all sorts of horror stories about them. I always thought those people were idiots, well not any more. I don't even really know how it happened but in a nanosecond I cut myself to the bone.6 stiches and a wasted day later I learned my lesson, clamp the work and use 2 hands on grinder
P1010986.JPG
P1010987.JPG
P1010988.JPG
We have tiltage. Its also adjustable up down, left right and front to back. Now I need to figure
out a way to latch this sucker
P1010991.JPG
P1010992.JPG
rear sway bar is done. It only took 2 tries.
P1011000.JPG
P1011001.JPG
Front swaybar just about done. Front and rear bars are Speedway hollow bars.
I can get different wall thickness to dial the car in.

P1011016.JPG
A 28" x 19" dual pass radiator should keep this thing cool. Had to weld in an elbow at the lower right corner. I couldn't locate
a tubular elbow so I use a aluminum water neck for a small block chevy. Had to make a shroud to hold the dual 12" fans. Things are starting to get tight up front now
P1010001.JPG
Chopped up the stock harness. It's amazing how tame it looks now. When you cut all the looming off and your left with a tangled mess you start thinking what did I get myself into.
P1010002.JPG
P1010003.JPG
Test fit before I start looming it up. The only thing I don't like is the big honken GM under hood fuse / relay box I have to use (only the base is in the picture).
P1010004.JPG
Made up some radiator hoses. I thought they were picture worthy.
P1010006.JPG
P1010005.JPG
Air filter and trans cooler mounted up
IMG_0009 s.jpg
I have the body harness just about done. This was a very tedious job. I removed a lot of wires from cicuits that weren't going to be used. There were a few mistakes in the wiring diagram that took a while to figure out.
IMG_0006.JPG
Just finished up the fuel tank. It has 3 internal baffles and a sump. The pump has a .250 fuel line. I find it hard to believe that will feed 450 hp so I made provisions for a .500 fuel line if needed.
IMG_0011s.jpg
Installed fuel tank and license plate holder / fuel door
IMG_0010.JPG
Fuel filler door open

couldn't resist putting on a cardboard air dam
