Like i said i broke mine that same exact way, and if he has a torsen, which i think me does, then in the diff there is a "blocker plate" to keep the two shafts apart. There is a small hole in the blocker plate just big enough for the right size punch to get it out. The only thing is you have to take out the other shaft and halfshaft to get the punch in there.
