My '85 CJ7 was in the same boat. I went to a junkyard and found an '87 Cherokee with power steering. I took the pump and bracket, hoses and the gearbox with the Pittman Arm attached. The gearbox on the donor vehicle was bolted directly to the frame with no bracket. When I removed my manual gearbox, I found the ps box bolted directly to the bracket I already had. An exact fit. I was told I would need a new bell connector to connect my steering shaft to the ps gearbox, because the tooth count was different, but mine fit fine, so I went with it. I did have to buy a new pressure hose because the one that came with the Cherokee rose too high to fit under the body of the CJ (a $20 part). It really was a bolt-on job, and I'm super happy with it. No problems at all.
