I have no preference for the type of transmission (I can drive both). I know the AX-4 won't work with the 4.0L, but thank you for that info! So, from the sounds of things, it was everything I expected. So, I can more or less just take everything from the XJ (axles, drive shafts, tranny, engine, transfer case, hubs, et cetera), and put it into the Comanche? My biggest concern is the shifters for the transmission and the transfer case. Would there be places through the body to put everything into the cab? Would I have to cut anything up? (Ignore this question if it sounds completely, well, dumb. I probably don't know what I'm talking about there). My brother got a newer Cherokee and gave me his old one, and I put in all of the things for the new lift kit. I've also worked in the engine before, and I'd like to put another notch under my belt with a project like this. I love the Chilton Jeep Guide.
