BA-10 to AX-15 conversion

I have a 1987 wrangler and I am in the process of swapping out my blown ba-10 for an ax-15. My question is that do i need to find an ax-15 1990 or earlier. I heard the throw-out bearings from a 90 or earlier 4.2 inline six won't work with like a 1996 ax-15. any suggestions would be great

Hopefully this will help. I am trying to get a head start on that same thing so I have a good idea of what I am doing. Hopefully I don't have to worry about it anytime soon though.

If you are going to use the internal slave cylinder, that is actually what you are calling the throwout bearing. It is different between the BA and the AX15.
If you are going with the external slave setup, you need an actual throwout, or release, bearing for a 94-95 model.
Year model-wise, the pilot bearing changed sizes in 92 from a .59" to a .75" inner diameter.
If you are using the 96 you mentioned, you will need to change the pilot bearing. You might have to get one machined to fit. A clutch kit for that should include the throwout bearing.
