The AX-15 has a removable bellhousing, so if you have the bell you can also source one from a V6-equipped Dakota of similar vintage, and I believe the AX-15 is the same gearbox as the Toyota W150 (can anyone confirm this?)

The AX-15i uses the "internal" concentric slave cylinder/throwout bearing assembly - it's the one that's a pain in the ****. The AX-15e uses the conventional "external" slave cylinder - the one that can be serviced without having to drop the wretched transmission.

The V6-equipped Dakota version will have the LA-block bellhousing pattern (MOPAR V6-238, V8-318/360, V10-488/505,) and it will need to be changed over to the AMC-pattern (Gen II/III V8, "Modern Era" 199/232/242/258 I6) before it can be mounted in a Jeep. However, the splines should be the same - 1.125"-10.

I am unsure about the input splines on the Toyota version, but it should be a fairly simple matter to sit down with a clutch catalogue and figure out which to use if it's not 1.125"-10.

The AX-15i uses a pilot (generally) of .585", while the AX-15e uses a .875" or so pilot. (The AX-15i uses the same pilot size as the BA-10 it often replaces.)

The NV3550 uses the same bellhousing and clutch fork as the AX-15e. The NV3550 was also found in V6 Dakotas, and I think some V6-262-powered S-series as well.

The transfer case adapters are 'clocked' flatter on the TJ and YJ versions than on all of the others - note this if you swap one of those into anything else. The swap goes the other way just fine - but if you put a "flat clocked" transmission in place of a "dropped clock" transmission, you're either going to have to redrill the adapter or "hammer massage" the transmission tunnel to clear the transfer case...
