Cab & chassis help

ok from using serch buttom i came up with 44 inches from back plate to back plate.
im picking up a c&c rear off a 96 monday morning

Will rear end fit direct bolt in 98 gmc dually?
Will 4 22s fit with 265/35/22 out bag with flip?

Any other info please chim in thanks

It will not directly bolt it. You can not run 4 22s out back. You Can run outside 22s and inside 16s.
The outside width of the rear on those trucks is around 36 inches. You'll have to move the leafs inside the frame rail which will cause other things to be moved.

I think there should be a stick on rear ends and running semi wheels and a break down on each.

If someone comes up with a good write up I'll stickie it. I've tried to write something up but lack the knowledge, when I get more time I will try to do it.
