Made the driveshaft. It's a bit of a conglomeration where Chevy meets MB but I got it within about .040" out of round. I have made lots of hybrid driveshafts and that is about par for my course and they never have noticeable vibration. Although I am concerned about my driveshaft angle and the parallelness of the tranny and the rear part of the driveline. Not too proud of the welds but I will clean them up.

The engine motor mount brackets are tack welded in and the motor is sitting in the car. Look, Mom, no hands! (or hoist).

Also shown is how I notched and rebuilt the front subframe. Later I will add a removeable brace that goes right between the lower A arm pivots to replace the strength of what I cut out.

The radiator fits too. Hoping one big electric fan is going to be enough. It probably won't.

Audi 5000/100/200 (up to 1991) had hydroboost brakes too. The pressure accumulator (sphere) was remotely located with a brake line to the brake booster, that made the hydroboost device itself pretty slim and neatly sized..

Couldn't get a GTO pan to work? That's what I'm running.

I almost bought a GTO pan but I checked the dimensions and saw that they are 1 1/4 inch deeper than the camaro pan. I think I'm going to notch my Camaro pan a little with my new TIG welder, assuming I can use it, and go with a narrow rear steer rack. Since I have to put a cross member under the pan anyway I might still be ahead on ground clearance if I can find the right rack. I am going to the JY today to go shopping for a rack.

Made a rear trans mount and lowered the car on its wheels. It sits higher than with the stock motor so I assume the new combo is lighter than the old one, although I don't have the battery or radiator in yet. Finished welding the floors back together. That was quite a job.

I went for a change of venue. I was working on it at my cabin in the mountains near Tahoe, where I can grind and cut without worrying about the noise. However, the garage is too small to work on the car with the door closed so I Friday night I went up and started the $500 van I bought a few months back. I had never driven it before so it was a little dicey. The heater didn't work and it had an exhaust leak. Three destroyed tires on the car trailer too. Luckily I had brought 4 used tires with me and I have a tire machine up there. I bought a plasma cutter and I hope that I can cut quietly enough to get it running in the semi urban environment in Sacramento where my condo is.

The first sidepipe is pretty much done.


I would show a picture of how I welded a piece of exhaust tubing to the cast iron exhaust manifold but you can't weld cast iron.

Got the radiator all mounted and custom AC lines made to connect the Benz under dash unit to the Chevy compressor and condenser. Sorry no pictures of that. Right now I am working on the fuel tank. I removed it, emptied it of gas and filled it with water. I kept the hose running the whole time while I cut a big hole in the top. Then I cut the part that holds the sender and pump out of the Chevy tank and bolted it into the top. Yes I was concerned about an explosion from the vapors and sparks from the drill or jig saw but it didn't happen.

here are pictures of my new steering wheel and the '99 Chevy truck instrument cluster, and my painted front brake calipers. I figure these two improvements should be worth a couple of seconds at the Nurburgring.

That arm should be on a site for stupidest mechanical work. Unsafe and poor handling.

Yeah but he just HAD to keep his AC. That and Im SURE there was no other possible way to make it work. Plus his welds are like totally stronger than the base material. Parts increase in strength after he welds them. Simply amazing.

His desire to do it himself outweighed commonsense. E 'nuff said !
