I just this very minute sent Jerry an e-mail with the part numbers I'm looking for. So who is the Jerry guy, anyway? Does he have his own shop?

I'll post them here, too:

8970629711 Cage Assembly (for rear differential)
8970752163 Coupling
8943762611 Nut
8944080851 Seal

I'm calling Merlin next. Apparently, the parts manager still had nothing more to offer.

Thanks for the help everyone!!
