Ok I just may aquire a 96 cop car real cheap. The wheelbase(115.9") seems real close to my Nash 600(112"). I was planning to use all the underbits including the frame, but the simple matter of 4" is unnerving.

Should I cut the 4" out of the frame, or just modify the unibody of the Nash, and pull the front end and axle from the cop car? any other suggestions would be appreciated.
