Hey everyone, new member here. I've been on the boards for a few hours searching and trying to get all the info I can but I'm at the point where I need some help. I picked up a 95 4x4 2 door a few weeks ago and recently hit up the junkyard for some misc parts. I managed to find a 2000 4x4 and with the help of a friend, we pulled the rear axle (minus the sway bar) for the brakes since mine are in need of replacing and I really hate working on drums. I did further research and the axle I pulled was coded GT4 with G80 diff (I actually went back to the junkyard a couple of days after we pulled the axle to get the codes) from a ZR2 where mine was a GU6. I understand the ZR2 axles are a little wider but should bolt right up. I understand that in order for 4x4 to work I will also need to take the front diff. I'm trying to figure out what else I will need to take from the donor so I won't run into any problems when I go to put everything together. I also understand the speedo will be off. What would be needed to correct it? Any help will be appreciated!
