There is no way around pulling the tranny the internal slave is on the input shaft. I suggest looking into the external slave conversion, though more money it is worth not having to pull the trans for the slave cylinder. It is also a good idea to go ahead and replace the clutch, its easy to do, and will save you pulling the trans again any time soon... Unless it has been recently replaced.
A few FACTS:
Rectangle headlights ARE kinda cool.
YJ does NOT stand for "Yuppie Jeep".
Jeeps should only have TWO doors.
You should ALWAYS wave at other JEEP drivers.
