i've not done it, but have done a bunch of research.
did you pick up a bracket kit from IRO? that should make life easier for sure.
i belive the 8.8 is a little narrower than the ZJ. so you will need some 1.5" wheel spacers to put it in spec with the front D30.
get one with discs if you can. (96 and up exploders)
for more info on it from people that have done it check out mallcrawlin.com or sites like jeepforum.com or nagca.com
good luck with it!
