recently i bought a 1990 F-250 with a 5.0 with the Mazda 5sd behind it. it also has the Dana 44 HD i believe.. after breaking both axles, and being offered a new pair(dana 50) from a 97' power stroke, i bought them.. now being offered a 460 and ZF5 tranny and transfer case... question is, besides changing motor mounts and computer, is there anything else i have to change? namely meaning, are driveshafts the same for the different axles, or the wiring between the trannies and transfer case?
