You will need a 23 spline input NP231 t-case, or a planetary set with 23 spline input to install into your t-case. I have both if your interested.
I also have an AX15 trans, shifts well, but other than that I have no info on it.
I also have a Down East Offroad Dana300 flip kit to put a Dana 300 t-case behind an ax15 (or any other Jeep 23 spline output trans) to make it a Drivers drop t-case.
I probably have other stuff as well.
