Erm, you know that hillbillies are generally in the Ozarks, right?
Seriously, you can usually score an AX-15 out of an XJ, MJ, or ZJ fairly cheaply, and it will hold up MUCH better than the BA-10 (I know this, I've been through FOUR BA-10's in my 88 XJ. The only
advantage to them is that I was able to pick up replacements for free.
(However, I've picked up one AX-15 for a small swap - set of cables - and another for free - drove the whole thing home. So, it can be done cheaply.)
Some modification is necessary to fit the AX-15 in place of the Peugeot, but the same parts may be used (save the transmission mount and transfer case input gear. The 23-sp input can usually be found cheaply - both of the AX-15's I got came with the transfer case anyhow.)
For information on the swap proper, start here: http://www.naxja.org/forum/showthread.php?t=70388
. That thread details a number of swap experiences - including my own - and give you conversion part information where needed (which are generally inexpensive.)
NB: The early AX-15 with the "internal" slave (AX-15i) can generally use the exact same clutch kit (including hydraulics) as the BA-10. The later AX-15 with the "external" slave (AX-15e) and NV3550 (which uses the same bellhousing and associated parts,) will require a hydraulic conversion and replacement of the pilot bushing, since it was used with a different crankshaft bore. But, all of that information should be in that thread.)
