I'm running a Dana 60 and 14 bolt. You could run a Dana 44 as long as you us chomally axle shafts you can run 39.5x15x15 tires thats what one of my buds run. You could go find a ford front Dana 60 just make sure its a 60 and not a 50, its will say on the diff cover. You could even run the ford rear axle thats with the front, one of my friends did that.
