Power steering box interchangeability

I just finished changing my pitman seals in my '78 and I gotta say I wouldn't wish that he#& on anyone. What a pain!

Anyway, got ahold of a power box from an '82 to keep as a spare.
But my '78 uses compression style fittings and the '82 has "O" rings. Is there an adapter or do I need to get new hoses if I ever want to use it? Does the pump also have an "O" ring connection on the pressure side? Would I need to replace the pump also?
I've seen these advertised as fitting "76-86" cj's and it seems a bit misleading.

NAPA has adapters to go from flare to oring and vice versa. The pump on the '82 has oring fittings also.

If you wanted to you could get hoses for an '82 and swap the fittings in the back of the pumps. You'll see on the back of the pump where the pressure line attaches that the fitting has a hex head on it that makes it removable. Take that fitting out of the '82 pump and install it into your '78 pump. Then both your box and pump use orings and '82 hoses will fit both.

Thanks CSP. That's exactly the simple answer I wanted to hear. Didn't want to have to get a new pump and hoses.

As far as the pitman seals go, I would probably do it again. Especially after I had several hours invested in cleaning and painting mine. And $6.95 for seals vs. $169.00 + for a rebuilt box. There are 2 washers and 2 seals to replace. Had to carefully drill a hole in the washers and turn a long drywall screw in them. Then used a claw hammer to carefully pull them out. The seals however were another story. Drilled about 25 holes in them and tried to hook them with the tip of a screwdriver which I cut into a hook shape. They did not want to pull out. Ended up looking like ground hamburger packed in there. Finally after about 4hrs. of fluid dripping in my hair and face I pulled the box off and tossed it on the picnic table. Had them out about an hour later. You have to be really careful not to scratch the sides of the pitman housing or the pitman shaft or you will end up with a permanent leak, which defeats your efforts. The new seals went in easily and it doesn't leak yet but time will tell. Persistence is the key. Got my seal kit from www.rigidsteel.com.
