I posted this on the pirate but thought I would post again here just in case.
Okay this is a shot in the dark, but why not just swap in a AX-15 in place of the AX-5. Then focus on a 231/300 doubler like Matt has in his TJ. Sound like a easy task since its all jeep parts but not sure how hard the swap is. Good luck dude.
I'm guessing that you want to do this because you either want the strength of a trans other than the AX-5 and you might be working to find a lower crawl ratio?
