Up for Sale is Advanced Adapters Kit 712563. Follow the link for details and instructions. 712563 : Jeep AX15 adapter plate kit to the Jeep AX5 bell housing w/ ext.slave cylinder (replacing AX5). | Advance Adapters
The kit adapts the strong AX15 transmission to your Jeep 2.5L engine (in stock form, the 2.5L is mated to the weaker AX5 transmission). Should work for either YJs or TJs with 2.5L engines.
The kit includes everything you will need to do the conversion. I can't get a good picture because it is installed in my Jeep. It will be removed this weekend.
I can include the AX5 external slave bell housing, clutch, pressure plate, and modified shifter tower if you need it.
You'll only need to supply the AX15 transmission, the clutch/master slave cylinder and reuse your AX5 shifter rod.
I've been running this kit in my Jeep, and it works great, and is easy to install. I'm just now swapping in a 4.0L engine for the 2.5L.
