Will a 97-02 tj power steering box work for my power steering conversion on my 85 cj7?

I think they are mounted differently, as well as the lines being different.

I would just get a H1 steering box, and the stock power steering lines will bolt right up. The box is a direct bolt in.

Looking for alittle cheaper way to go. Didn't want to spend $105 on a core charge since I don't have a core.

I have never heard of anyone doing that swap, but then again up until a few months ago I di not hear of anyone do an H1 swap. You really need to look at the specs of both boxes and see it the spline counts are the same. But for some reason I think the steering shaft mounts differently, but I could be wrong. Sorry I can't help but if you can get it to work you may have found another option for eveyone. Its going to come down to homework. Have to do the homework.

I guess i didnt really make myself clear. My swap is going from manual to power steering on a cj7 and was just curious to know if the tj box would mount up. I see the input shaft on a h1 box is 32 and a cj box is 31.Is there an adapter to go to different spline counts?

What is the spline count for a TJ box. You need to know the input count and and pitman arm count. When you do your seach, check may sources as some seem to differ.

I always see TJ guys swapping their stock boxes for Dodge Durango boxes, so the TJ box must not be so great to begin with.

Well did some research today and it looks like the J20 power steering box will hook up the the stock cj7 manual steering shaft coupler. Only thing I couldn't find was what year model J20 box I can use. Any help would be appreciated.

The only thing that differs based on year is the hose fittings. Any '80 and up, whether it's a CJ, J20, or whatever uses the same size metric Oring fittings. That's what you want.

Since you have manual Steering the J20 or even the J10 box is a good swap. Just make sure you get the Box and the pump that match. Meaning if you get an 80's on up box get an 80's on up pump. This way you will not have issue with the hoses.

Well it looks like not all year models of j20's gear boxes will work with a manual gear box coupler. My manual gear box coupler is too small to fit my new power gear box. So now I'm down till I find the larger one. 😡
