An FYI on the Savvy nutsert install tool; I ordered it, and it turned out to be for one of their products that uses nutserts, not the t-case nutserts. It's much to small; no worries though, the "tool" is easily made from a few pieces of hardware from your local hardware store. This thread has more than enough info for you:
Nutsert for Transfer Case Removal and Install - JeepForum.com
The part numbers for new nutserts are there, as well as information on how to remove/install the nutserts and how to make/use the tool.
