Some info about 8.25 diffs.

To clarify.....

Disk brake axles and 8.25 sure grip carriers that work on our classics are not found on the same vehicle.

You would need a 96 or older axle for the carrier and a 2001 or newer axle for the disk brakes.
(might not be 100% on 2001 being the change to rear disk- going by Dakotas)

I pulled my last set of rear discs off of a '96 Grand Cherokee, but I see part listings back to '94... Keep in mind these were optional and not standard equipment. I *think* Liberties (and their twin cousin, the Dodge Nitro) had them as standard equipment.
And a little more info as I go through my notes-
Grand Cherokees had 11 1/4 dia. rotors
Liberties had 12 3/8 dia.
Dakota/Durango used rotors a hair over 12 1/4... but had six lugs. I've used the 5 lug Liberty rotors with no ill effects.
