The Jeep came with a BA-5 which is a Pego 5sp. The only reason for it now is I have it, and the to trans tunnel didnt need to be modified. My goal was to go to the AX 15 which would use the same transmission mount as the BA-5 but would require opening up the trans tunnel. They share the same bell housing. Looking over Jeep threads, there maybe an option to use a Dodge bell housing to relocate the starter to the driver side. But if its at the same heigth lining up with the pittman arm this time, then there is no benefit.
