Sorry for the very late response, but I check in here maybe every couple of months now. Becoming a family man kinda changed things for me. <img src="/forums/images/graemlins/smile.gif" alt="" />

I think you're on track, and it sounds like the other guys have answered most of you questions. With my swap, I opted not to keep the Mitsu t-case because
1) it's very heavy and to do it properly another crossmember probably should be added
2) the cable shifter for the NP231 was ideal for keeping the shifter in the stock location as well as rigging up one shifter to control both t-cases
3) I didn't want slip yokes. If I had to remove a drive shaft for one reason or another, the t-case keeps it's fluid. Also it's easier to get a stout aftermarket drive shaft (I highly recommend Tom Woods for this, his shop was great in helping me out) and the u-joints, etc are available at any respectable parts store.
