Ok guys maybe this is an easy one. My 80 GMC 3/4 ton dana 44 has a bad housing. I picked up a dana 44 out of 3/4 ton 75 Chevy to swap out with. My 80 comes with a 4:56 ratio, the 75 has a 4:55 in it. My corp 14 rear has a 4:56 in it. I'm I dreamin to use the 4:55 and just slide the assembly under my springs and be driven in an afternoon? Or do I have to swap my guts to the 75 housing. Or do I have to find a 4:56 ratio that fits the 75 diff?

Any insight would be greatly helpful
