I have a chance to trade brakes with a totaled truck. I want to keep my 80 but I would like the disc set up off the 70. My truck is single wheel as the other truck is too.Will everything bolt up? if so do I need to swap the hubs to?
 
Look at how the brakes mount, that should tell you. The back plate on the drum has 4 holes, the disk are different, if I recall correctly.
 
Disc brake and drum brake parts are not interchangable.

The axle housing are different.

Bouth back plates are with 4 holes, but the bolt layout is different
