ok here we go i have a 1996 f350 4x4 cc 7.3l with a e4od (which is going to be the death of me) what i have found is zf5 out of a f450 that i believe came mated to a 460 motor now this transmission is a 2wd my truck is 4wd which leads me to my first question:

What tcase do i need to make it a 4wd?

The F450 zf5's had a plate in the back so i could accommodate some kind of e brake please feel free to elaborate.

Then i found an 1991 F450 Diesel 7.3l Turbo with all the pluming cross member and petals still in the truck the only thing missing is the transmission.

which leads me to my 2nd question
Will the parts off this truck work on mine and what will i need from this truck to convert my truck to a 5 speed?
