That would be a good donor to swap things into your Jeep, if you want to go to a 4.3, the stick will be a good trans, and the case is a np231c, the only real differences between your case and that case is that case has 6 planetaries to distribute the input torque better than the 3 in the Jeep case, other than that I think maybe the switch on the side of the case for the 4x4 light will be different but that should be easy to swap out for the current one you have in your case now, if it matters to you.
