You'll do better with a phone call to Georg (@orangefj45) . I don't think he spends much time on MUD.

Talked to Georg yesterday. Sounds like my option is to purchase a new complete front diff. He had a take out but by the time I purchase it, ship it then refurb the bearings and seals I can purchase a new unit. If I needed to do a locker of regear then used would be the way to go.
