jeep cherokee rear in A body

explorer 8.8 ,does this rear need a lot of mods, I noticed some explorers at the yard , I looked but thought mounts were different, I heard if you go disc you need proportion valve , I'm not sure on all this , it's great to get more info, u pull it yard charges 60 for 5 bolt rear so I could experiment for cheap,but so far jeep looks easiest
