I am planning on swapping frames on my 1987 numbers matching GN because I'm restoring it and the current frame it sits on is wrinkled in the front. It was obviously wrecked and straitened before I bought it and I don't want to put a lot of time and money restoring a car on a wrinkled frame. I have the opportunity to buy a pristine frame from a 1988 Monte Carlo SS. Will this frame match mine identically?
