X 2, I want to put rear discs on my XJ D44 as well.

Depend what year your rig is...95 or older?

Go find a 96+ Xj, Zj or WJ.
Grab the whole booster, its a dual diaphram setup and is tones better! Also the rear disks are lovely..and if you get a set of used rotors, just turn them and you should end up under 150-200 for that whole swap.
The brake booster is a great upgrade, as well as the disks.

I know the 96+ XJs don't have rear disc brakes. No XJ Cherokees ever had rear disc brakes and the first year of the WJ Grand Cherokee is 99...so, I'm guessing what you are saying is any 96+ ZJ with rear discs can be used to rob the rear disc rotors, calipers, backing plates, master cylinder and booster out of. Did I get that right????

Ya I should of been more clear.

84-95 XJ's has a single diamphram booster..so get any booster from a 96+ Xj, ZJ or Wj as a brake booster upgrade.

And I think it was 94+ on the ZJ's for rear disks. Wj rear disks are different! I know I pulled mine of a 95 ZJ..
You can also get them off a KJ aka a Liberty! Or a crown vic/Exploder.

Thanks so much for the information. You are actually the first guy to clearly answer that question for me. However, I have a D44 out of an 87 XJ in the rear of my 91. I believe Tim's (Cherokeefever) rear D44 is out of an 87ish XJ as well. Will the 94+ ZJ brakes still bolt up?

Anyone know a good combo for Dana 60/44 Haha?

Yes they will be bolt on.....except for 1 minor thing..the center hole, may/maynot need to be trimmed slightly but otherwise bolt on!
