This is the before photo! Car came from NM. It has a smoke bomb of an engine with an aluminum head and Weber carb. The interior has all been redone. There is bondo on this car in several places. I haven't seen much rust, but will find out soon! Curtis asked about the Mirror's on this car? I have know idea what car they came from? Found alot of bolts loose in this car all over the place. The suspension is like a sponge. This will all be changed soon. After Omaha meet were diging in on the tear down.

Brenda's 2002 Ls1 is in the warehouse! Will take off alt, ac, pwr steering, idler pully, exhaust manifolds etc... to lighten up. We also recieved the aluminum drive line that came out of the same car. It will then be put into our small work trailer and go home to our house. T56 shifts well right on the pallet. This engine seems to have an SLP crank pulley on it with a reusable ARP bolt. When I pulled off the exhaust manifolds, looked at all the ports, engine was running well. Pulled a car fax on the vin, engine, passed smog on all years that it was on the road. What is nice I have all the top end parts from my TR6 ls1 that can be re-worked instead of buying aftermartket parts.

Moving engine and all lift equipment from warehouse to the house.

Started taking off the front bumper and front valance in the evening. Found some pretty awesome looking bondo!

Okay!! I have Brenda here on Fathers day digging in before it gets hot today. She took off the back bumper by herself. How cool is that to have a wife like Brenda. I believe she will have very good knowledge of a GT by the time this car is finished

Brenda already had the tail light's out, reverse light's, and side markers done before the rear bummper.

We really enjoyed fathers day together :-). As the day goes by and the tear down continues.

Stuff was coming out with speed and being bagged and labeled.
2013-06-16 14.04.15.jpg

Front hood, head lights, side markers, turn signals, front bumper, valance, and recessed grill, all removed. Old office chairs work great for this kind of work. You can roll around the car and to pick up a tool or two to save your back.

Pretty much striped out all the interior except the dash.

Started taking off some of the thick tar matting to check for rust. No rust here and hardley any surface rust.
2013-06-16 18.54.35.jpg

Orange or a Red color, kind of a color blind here so Orange/Red

The spare tire area didn't have any rust either.I did smell some gas back there. So I'm wondering if the top of the fuel tank is rusted some, but the smell of gas is there. Need to drian 1/2 tank of fuel out for the lawn mower.
2013-06-16 18.55.03.jpg

This will be next for another day soon. We had a cold one for the days progress, and for fathers day!
