Will an AX-15 from a 92 YJ fit in my 99 TJ?

Is the 92 internal or external slave?

Internal

The AX15 was used with an internal slave/throwout assembly up through the 1993 model year. In 1994, a more conventional slave cylinder and cross-arm were used. The input shaft is a 10 spline x 1-1/8" and its stickout length is 7-1/2".

That may be true but they do get swapped around sometimes
 
If it’s stock it’ll be internal slave. If it is, then you’ll need to convert it. You can take the parts off your old 99 trans if you want, your stock 99 would already have the parts needed. Bellhousing, front bearing retainer & snout, the external slave itself, clutch fork and associated hardware, and the throwout bearing.

Not unless he has some sort of vision that can see stuff from hundreds of miles away...I have torn down several yjs that have been converted to external slave..its a jeep people swap constantly and nothing is as it seems.

That is true, but anyone can argue that all day long about anything really, especially on a vehicle as old as a YJ that could have had anything done to it by now. Could say the same about the engine, axles or really anything else too. Of course the trans conversion is more common, but seems like the vast majority are still stock, so most would assume to expect the stock 92 setup, not what “could be”.

Either way it doesn’t really matter though. If it’s internal, he can easily convert with his own existing parts. If it is external, then great, no need to worry. If for whatever reason the 92 has one of the old transmissions with the smaller pilot tip, he’ll need an adapter pilot bearing/bushing to fix that.
