You could do a 14 bolt SF swap out of a OBS 4X4, that would swap right in after some minor mods. Depending on what you use the truck for you could just re-gear front and rear for the added tire size and rolling mass. If you are mainly street, and don't get too crazy off road the 10 bolt will hold up just fine. My Z has 6 inch pro comp, 3 inch body lift, and running 37X13.5 R20 Nitto Mud Grapplers with the 10 bolt re-geared to 4.88 with a detroit true trac. My truck is my daily driver and off road toy, been running just fine with no issues for going on 4 years. The main thing is to ditch the g-80 limited slip, g-80 failures are pretty common in the 10 bolts....
