This is why I asked, "Can anyone confirm one way or the other with certainty?"
For future reference, if anyone runs into this issue in the future: The NV125 is used in both the 3.0 and the 4.4 (00-mid 03), and are interchangeable.
My issues are taken care of, but I still wanted to get to the bottom of this, as transfer cases out of the 3.0 (even though the same) are seemingly much easier to find.
