I just had one of these gone through after breaking an axle at the drags. New axles from Dutchman, new clutches, bearings, seals. It is a Dana 60, I went with a Rough stuff cover. The ends are unique although parts are available. The ends have seals inside the tube as well as in the retainer, so you must pack these bearings. They don't get gear oil down the axle tubes, (sealed). I kept the drum brakes, so I didn't have a problem with caliper mounts but I am sure they could be easily fabbed up. You must be careful though because the bearing preload is set with shims and the brake backing plate itself is a shim. So That thickness of the backing plate must be kept in the picture or the bearing will either be too tight or too loose.
