The incredible folding Cuda!

Dang, sorry bout that. The good news is these cars dont need to be lazer straight.

Pull the engine, release the T bars, get it as straight as you can then tac in some cheep steel, angle iron, 1x1 what ever is cheep and go for it.

Im guessing you dont have a frame table..(i dont)

Put a 8' level on your garage floor see if its flat front to back and side to side. Start pulling numbers off something and go from there.

This is a hard one, like we say. Sometimes you just gotta pick a number and call it good. That becomes your number and work off it.... sometimes that's all you get.
