If 100a is what you're looking to upgrade to, I'm pretty sure a few brands have parts that list as fitting these 4.0's in these year ranges. I have a remanned AC Delco 100a waiting to go in in the spring and that was only $80 on amazon. Apparently it's a direct fit. If it lists as an OEM part, it should fit without modification. If it needs a bracket, it's probably not for these exact year/engine, but is close.
I'd check around for other ones - they're usually remanned, but you can find a 100a for under $100 that will list as an oem part.
On rockauto there's a Remy and ACDelco 100a remanned both just under $100.

100a is still more than they came with stock. The more the better, sure - but even the 100a's are ~$100, and anything bigger than that is more like $200 usually. I looked into the green monster or whatever....meh. 100a is plenty unless you're running all sorts of anti-apocalyptic junk all over your jeep.

CS-130 is the model of Delco alternator on an 88.
Should have no trouble bolting in a higher output one.
99 is a different animal entirely, so disregard the post on that.
Have you upgraded your cables already?
