Easy answer. Locker. You'll have to reset the gears anyway, so get new ones to reclaim that power band. Anything worth doing is worth doing right, save up and get a selectable locker for the rear and an S35 kit, or an 8.8 if you dont mind losing some ground clearence in exchange for strength. In the end its cheaper to do something right the first time as opposed to the second time. This true for jeeps, college courses and marriages as well.
