>From what I found doing searchs on car-parts.com is no hits on the 8.5" axle in two wheel drive applications at all. Maybe they are out there, haven't tried local yet, but the only listing is a 3:08 gear. I prefer 3:31-3:55 range with the 2.95 first gear trans. The 8.5 mainly went into ZR2's and the are like 8" wider then the two wheel drive axles!!!

I hadn't thought of the Astro, But I need to find width and disc brakes.
If I'm going to upgrade I want it ALL! :]
When I get the ZJ rear discs for the XJ I may try a quick test fit on one of my AMC15 axles as dependingon offest and the hub diameter the ZJ brakes may bolt onto the AMC15. That would be easy, but still leave the two piece axles. which I figure are the weak link in the picture anyway. I'm somewhat afraid that once I put the World class T-5 in it I'll be a little more prone to dump the clutch once and a while! With the 255/60/15's and the 4.0L making as much power as some of the small 8's. I'm guessing it won't be too long before I break SOMETHING!

As far as I know all Jeeps use solid unvented rear rotors.
I'm in the process of buying a set to swap onto the rear of my 97 XJ.
I prefer the vented setup on the S-10, but want a bolt on setup for the XJ.
I don't care about the 4 3/4" bolt pattern as my wheels are dual pattern, plus if the S-10 axle is only an inch narrower I can use 1/4" spacers on each side and be good to go. The first wheels I had on came with 4 1/2" backspacing. the current wheels are 4 1/4" two 1/4" spacers would do the trick.
