Will a 90 AX15 and 231 work in a 94XJ?

I can't find a 231 for my 94 XJ that will bolt up to my AX15....I can get a 90XJ with the AX15 and 231 for $150. I can't see why it won't bolt up...but will the plugs on the t-case work,...the 90 is also an 6 cyl......

The AX15 will mount to the NP231. However, it's extremely important to make sure your NP231 was made to mate up with the AX15. By that I mean the input/output shaft length and spline count has to be compatable.

All AX-15s have a 1 1/8" 10 spline input shaft and a 23 spine output shaft. If your 231 was originally mated to a AX15 the swap is fine. If it was from the AX5 the spline count and the length will be wrong...

Just my humble thoughts.
