@autopro - yes I have interior pieces, but the pieces are going to need a lot of work. As you can see my car is a RHD (I saw debate on this, it's just how we refer to it here - the steering wheel is on the right when you are in the car) so the dash will have to be destroyed and remade. Not sure what I'm going to do for interior to be honest. I got a really good deal on some race seats that in a pinch will pass off for lambo seats, and that's as far as I've made it on decisions for the interior.
@apsara - your post on how to stretch the car and keep it aligned saved my life. I did exactly that with square tubing though instead of round. It was just easier to weld to the car. I did a ton of measurements and the only thing that happened is it sagged a bit on the supports. I supported the car and re-measured before I welded in the sleeves, then the stretch metal. Turned out really well. I think I have more pics and maybe even a video if anyone is interested. I used a jack-all with a piece of 2x1 tubing under the center console, and a scissor lift (used for spare tires) horizontally between the front section and the rear section of the roof. I did not cut off the roof until after the whole stretch was done. This was a very important measure for me to make sure there was no sag.
The main reason for the lift was all the work that had to be done under the car. Also, I have never felt comfortable working under a car on jacks. I'd gladly pay $2000 for peace of mind, an extra parking space, and a great deal of time saved. It means something will have to wait to get done, but it means I could progress without frustrating myself.
The place I cut actually made the tank re-install really easy. I cut in the narrowest part of the console AFTER the fat part of the tank. So it made my decision of where the tank was going back in really easy. The fat part was still fat, the skinny part was where my extension was, and the fat front (the tank is like an hourglass) was back around where the handbrake is on the inside of the car. But, since the handbrake comes down through the floor, I just used the scissor lift to fatten out the area, and the original supports of the tank still worked excellent. I can take pics of under the car if anyone would care.
