I have an Eaton HO72 with 4:10 gears. The truck is a dually with a flat bed. I intend on putting a Caddy engine in and want something with more highway friendly gears. Possibly in the range around 3:50 to 3:73 with a posi. I believe 14 bolt rears up until '86 or so are a direct bolt in, is this correct? Does it have to be off a dually truck or can it be a single wheel one ton. (is there a difference). Will newer rears fit? I could move spring mounts. Are they available with disc brakes? Any info or input would help.
