The Aisin 5-speed (I'll see about getting a model number posted as soon as I can find the CD) was stuck behind the 3.1L and later 3.0L intercooled turbo-diesel Troopers so is a pretty stout unit. AFAIK, the t-case isn't integral and I think I reasoned out how to mate the TOD to it using either an off-the-shelf adapter or one was fairly straightforward to make. Again, I'm operating on memory here and haven't thought in this circle for a while.

It seems almost as if the US Isuzus got the weakest drivetrain components since we got the weakest engines in most cases, so I've been eyeballing Trooper front clips from the UK and Japan. I've heard that stuff like that may be getting either more difficult to import or pricier depending upon which overbearing governmental rumor you like best.

Again, grab the CD shop manual for the JDM/UK Isuzus. I drooled my keyboard after I got mine!
