Hey Guys, I just purchased a running/driving 65 GTO 2 door sedan that needs restoration. I figured that I could drive as is for now, but be building a nice chassis for it on the side, and when the time is right pull the body off the current frame, do the body work and then set back onto the newly built chassis. So here is my question.....which other GM A-Body frames will interchange? I have a friend willing to donate the frame from either a 65 Chevelle SS or a 66 El Camino. Needing to know what will work with the least amount of modifications. Thanks for any help y'all can offer.
