Thanks Ed. A friend just advised he restored a 56 Chevy several years ago and put a 78 Chev shortbox frame under it? The truck pretty much was a direct bolt on to that frame and allowed for disc brakes and modern power steering! I know that it would be nice to find a 1955 frame but if not, the 78 frame could also be an option as there seems to be several available at reasonable prices close to where I live?
