I had this same problem a month ago. If you search you'll find my thread with lots of info.
But I ended up calling advance adapters and ordered the correct one.
Ok I finally solved the alignment tool problem. But now I'm having a pilot bushing problem. Anyone who's done this swap have the part number for the correct one. 3 of them I picked up for a CJ5 have a smaller diameter center hole. I'm about to just hone it out so I can get this jeep running
Not yet, the first two I ordered were wrong. And the other two seem to be taking longer to come in. That's interesting. That's actually a good idea. Never thought of that.
I'm in the process of swapping the mj over to a AX 15 I've got the CJ-5 pilot bushing but what Clutch alignment tool do I need? The parts store lists 3 for an 87 Comanche.
