Sprung over suspensions generally have axle wrap issues when exposed to high torque situations, doesn't matter if it's a Jeep or an old muscle car; you're going to need a traction/anti-wrap bar. It's pretty easy to make your own, but there are bolt in kits avaliable.
Word of advice though: if you're going through the trouble of fabricating and welding in a traction bar, don't do it to the Dana 35, get yourself an 8.8 in there.
