changing a 4wd rear axle to 2wd

My '80 C10 has a rear end assy. from an '86 truck (3.08 gear, 10bolt). I'd like to change to a 3.42 rear, but 2wd's with that ratio are scarce here in N.E. On the other hand, a 4wd rear with that ratio is quite common. Other than axles (6 lug vs. 5 lug), are there any other differences that would prohibit using a 4wd rear in a 2wd truck?
