I baught a business coupe a while back and im ready to work on it. the person who had owned it before me screwed the stock frame all up, cut the cross member out and squeezed the rails together and put a s 10 clip on it. ITS BAD. Im going to bye a stock 48 plymouth frame for it from a guy here in town. I looked up the wheelbase in a book and its saying that 46-48 all models club coupe, buis. coupe, 4 door and 2 door sedans were 117 wheel base. the one im going to buy is a 4 door. Im just wanting to make sure this is right???
