It's definitely a Dana 44 (as usual, Jeffy is correct). Both my Jeeps have 5 speeds, so I shouldn't have an issue there. I have access to a plasma cutter, so I can rough cut the radius arm brackets and then fine tune with a grinder. I am leaning toward using the D44 in my TJ to replace the low pinion D30. I have an 8.8 with 5 on 5.5 shafts ready to go in the rear, I'd just need new wheels. I know there are lots of tricks with the outers (high steer, disc brakes, etc.) and I'm looking at RCV axle shafts.
