Just did the one on my '96 XJ awhile back. Went with some O'reilly's organic clutch because 1. I really needed it and didn't want to wait around for parts in the mail 2. It had a lifetime warranty and 3. My buddy who I go to school with also works at O'reillys and hooks me up with the military discount (even though I'm technically a vet.) No problems so far, knock on wood.
A few side notes from when I did mine-
Agree with machining your flywheel. Mine cost me like, $40, $45 and an hour or so of waiting. Make sure to mark it with a bit of paint before you yank it (paint marker works.) Would not recommend unbolting the flywheel bolts with an impact gun as my understanding is it can f*** up crank bearings (they're kinda important when your odo says 300K+ and you're trying to make your engine last, like me.) The bread and/or grease trick for popping out the pinion bearing is BS. I just made a greasy, gluten-y mess when I tried it. Just rent the tool if you haven't got it, they'll refund your money when you return it. I was able to keep my NP231 attached to the transmission, no need to pull it. Mitchell says to replace your flywheel bolts with new ones, but that's also BS IMO. Seems like the only place that has them is the stealership which means they will charge you like $5 or $6 apiece for them and is pretty much guaranteed NOT to have a complete set of 6 on hand. Carefully inspect your old ones, as long as they're not stretched and the threads are okay, they should be good-to-go with a bit of Loctite. Now would be a good time to inspect your clutch pedal, particularly the Z-bar. That's what happened with mine, Z bar got all bent out of shape, couldn't get the clutch to disengage. It's only got half of a circular weld attaching it to the pivot pin and nothing on the back-side of that. If you can, make/complete those welds, and welding a bit of reinforcement in between the Z-bar and main clutch pedal arm isn't a bad idea either. Don't worry too much if the clutch is shuddering a bit after you replace it. My understanding is that's just the flywheel and friction surface of the clutch sort of "mating" to each other and will go away after a bit, typically a few weeks to a few months.
