No sweat on the conversation detour, pretty much all the important stuff is in the first few pages anyway.
The input shaft, which is what needs to be changed to put the 4 cylinder t-case behind the AX-15, is quite small, so if it had to be shipped it should be fairly inexpensive.
Once again I am using basically stock 4 cylinder t-case parts behind my V8 and haven't had one problem from it yet.
Something I just remembered that I should bring up. Motor and trans mounts. Since my swap I have literally ripped all of mine apart, on different occasions mind you. I found some motor mounts that have built in hooks to limit travel and ended up going with a poly trans mount as the rubber ones just couldn't hold the power.
Cooling system is still working great. Other than a worn out engine (which I knew about from the start), a bent wheel (no clue how it happened), the mounts and my axle hop (which seems to be cured by the ladder bar) I haven't had any problems with the swap. Still enjoying the power and noise and not regretting it one bit.
