Need help with rear disc brake conversion

The Dr. Diff 10.7 and 11.7 inch rear discs work with either the factory tapered roller or aftermarket green bearings. Only the 11.25" kit requires green bearings.
Or you can just go to the boneyard and grab the rear disc setup off of a '98 or earlier Jeep Grand Cherokee or a Jeep Liberty. Darn near bolt on an 8.75 with green bearings- just have to drill 1 hole in the backing plate, and some minor fab to hook up the parking brake.
