well iff you have 3.55's in the axle you would be getting, you would need to regear the front, or get another dana 30 from a automatic cherokee(97+ had high pinon dana 30's) and could swap it out, unless you wanted to just regear the one you have now, and also you could have a 29 spline 8.25 some kater 96 productions had them.

lol, ...oh yeah, Im 4WD. I wouldnt own anything else, because if Im not in a 4WD, I am in a FAST CAR, and that means I am in TROUBLE. Due to the limited number of cops to observe me doing stupid crap off-road, I prefer 4WD these days. I value that driver's license, and I hate fines. I must have bought at LEAST two new NJSP police cars with the fines Ive paid. ....Not since I went 4WD, though.
I scoured the junkyard today, and I actually had my eye on a D44 in a loaded late 80's laredo limited something, (mustve been a beauty in its day, Woodgrain paneling in and out, full power and options, towing package, big alternator (I scored it) and I reckon It might've been up country)......but I saw it a month ago, went back today...AND IT WAS GONE. (I had actually piled doors and crap around it to hide it for myself. Dammit!
....So, the next best thing. A 29 spline eight and a quarter with limited slip. I was planning on regearing to 3:55s anyway, because I am on 31's with 3:07 gears, 5 speed, and a 99 intake with a bored TB (high RPM, highway-friendly induction system).......... So, . Ive got NOT MUCH for power down low right now, and I gotta spin the whole mess up to 3000 RPM just to get it moving anyway. Great on the highway though. 2100 RPM at 75 MPH with plenty of power there and 23-25 MPG!!!
Cant wait to get some meat on the ground, and a set of 3:55s might get me back in the neighborhood without buzzing the motor too much.
IMO the limited slip was built to fail. And I didn't think they offered that in the 8.25? I thought that was only d35's that came with limited slip. If someone knows let me know.
If I were you, I'd take the time to pull out the shafts and count it up. If you have a 29 spline setup already, the only thing you would need to is find an axle with better gearing. Doesn't matter what year. So in my case, I picked up a $125 axle was a 27 spline but had 4.10 gearing from one of my local junkyards (had I gone on a monday or a wednesday it would have been half off!). I just pulled out the carriers, switched the ring gears, then put the 29 spline carrier and shafts in the 4.10 axle, and kept the old housing as a spare in case I bend mine or something.
The locker will be what is most expensive, so in that sense, getting the 00 with the lim slip may just be worth it. My experience with stock limited slip is that the slip is not so limited. Mine doesn't even work anymore in my D35. I'm just waiting to get the spacing for the r&p measured on the new axle before I swap it in.

My sig got too long. So we'll just say it's Friggin' Sick.
I've found the 8.25 (with and without TracLok's) for as little as $85, complete, around here. And not crap, either. I found a 1999 D35 for a friend (it also had a TracLok that actually worked!) for $50 about 17 miles away. I don't think it would be worth your while in terms of gas$$$ or time to come up and get one, and shipping would make it no cheaper than the one you found, but if you're going to be in the neighborhood anyhow, then by all means holler and I'll show you around. Toss one (or more) in the back or on a HitchHaul or something and good to go.
