Stock rear for your truck is a 8.6" 10bolt 30 spline.

Thanks for the info. now i guess its time to get dirty

If your big into wheeling hard, in mud or rocks, watch out for that G80 locker in that rear end, it is def. the weak link in that rear axle. Especially if your runnin larger than stock tires.
