2wd 14 bolt rear axle fit on 4wd?

[ReeseBobby]

Hi guys,

I'm trying to get my stuff together for my axle swap on my 1970 C20. I've got a line on a 14 bolt rear axle. It came from a 73' 3/4 ton, but the perches were adjusted and put onto a 72' 2WD 3/4 ton.

My questions are: Is there any difference in a 2WD rear vs a 4WD? And if the perches have been adjusted to fit on a 72' 2WD, will I need to do anything besides bolt it in on my 70' 4WD? I have a leaf spring truck and that's what it came from. Anything else I'm missing? Thanks!
