I recently acquired an AX-15 transmission and want to swap out my current BA-10/5 for it. I don't have any donor parts from the original vehicle, so I need to make sure I purchase all the correct components.

 

If I purchase this adapter, I should be able to use the existing x-member and mount, correct?

And I know the 4wd shift linkage is different, so I'll need something like this?

The X-15 was pulled from a '92 XJ, so I believe I should be ok with the existing hydraulic throwout bearing (I believe '93 and later need the external slave cylinder).

 

I'm placing it in a 1989 MJ, and from what I've read, the later BA-10/5 outputs could be either 21 or 23 spline, so I'm not sure if I need a new input gear for the t-case.

 

Also, is this the correct pilot bearing I would need?

It should be. I don't know how to read that scale so I can't verify. But as far as that mount goes I though I would be able to use it as well but the answer is no. A lot of the trucks are different from one another and i was able to put put the rubber mount on the bottom of the ax15 and get it into the front 2 crossmember holes without any modification

Yeah, calipers aren't too straightforward, but because it's exactly .750, you just read off the zero on the right. If it aligned with another number, that would just indicate a fraction, like .755.

 

And you're implying that the mount is hit-or-miss, and it may fit perfectly, but could also need modification?
