Have you found a lift yet? If not, go to
Downey Off-Road. They have more stuff than you know what you want...I'm working on my 1990. Some of the stuff I'm getting from there and others I'm getting stuff from is Cage Off-Road for the solid axle conversion. But I'm looking at 5"-6" with that solid axle and dual transfer cases. So mine will be a little more extreme for serious rock climbing.
Good Luck
