Durango Steering box

im going to be upgrading my steering box to the durango box since its time to change mine and to help with running 35"s. my question is will a stock pitman arm from a 1997 grand cherokee fit on it? im thinking since the grand cherokee pitman arm will fit xj box, then it should fit the durango box?

Yes it will, and the ZJ pitman arm (according to research on ) will result in a 1" drop, so you will have to deal with steering geometry. You didn't mention any specs on your rig. How much lift, etc?
