You need the rear axle from a zf-6 speed truck. You can use a zf-6, but you wont have a speedo, because it reads from a pick-up in the axle housing, not the rear of the trans.

You also have to use the SD transfer case due to a difference in the splines connecting trans to tc. There is a member on here that did it,he had the truck up for sale lately....

2wd or 4wd?

Some 7.3 IDIs had the speed sensor on the diff.

No you cannot just swap them out. They're too different. "jaybee" is a member here and did fab up a ZF6 swap to his 7.3 IDI. He also has pictures in the photo gallery here. He's the only one I've seen do this swap.
