I put a 30 in my 92 2wd to do a 4x4 conversion. I got a hp30 from a 95 classic cherokee and it did not have the disconnect. I love it like crazy, but don't put alot of money into it. I did mine for under 1000 and it was harder than it seems to do that cheap. If you're going to spend more than that i'd say go with a 44 from an old highboy or something. They can be found without much trouble around here, and if you put more than 1000 into a d30, you could have way more axle for that same price if you found a 44 that already had the correct gears. Most jeeps I found had 3.07s.
