I have a 77 F250 4wd Highboy, well it started out that way a lot of mods have been done over the years. It now has a 460 w/ a C6, a Cab & Chasis dual rear and a flat bed dump. The cab is beat, I can get a clean & strait 64 cab cheap, just wondering what it would take to get on the 77 chasis, narrow frame, w/ the 460. I would also like to put a power steering gear out of a 78 if possible. Thanks for any comments / sugestions, Bryan
