well....... the big question is.....
what do you want to use the jeep for?
There, I said it, so nobody else say it!
Acually, im not sure what you want to do.
What do you want to swap? The axles? Do you want a locker? Change gears?
Do you want wider axles? Bla bla bla
Im looking to do an axle swap. Im wanting to go full width so I will either do wagoneer axles which I think are dana 44 or full size chevy blazer axles which is a corporate 14 bolt and a dana 60. Thats a bulletproof swap.
I hope my rambling has helped
