You can even use the later model 10 bolts if you want. I think the 88 -91s have 30 spline axles on the 10 bolts. Earlier 10 bolts have 28. I'm pretty sure the later dana 44s use axle shafts with bigger u-joints. 10 bolts are easier to swap gears in also. If you want Dana, I would look for a late 70s model.
