    you have to get one from a 73 - 80

    81 or 82 is when they changed the fittings from flare to 0-ring....unless you want to change all your hoses also, get one from above said yrs.

    Very important to remember that! I got a steering box off a 76' blazer because mine leaked terribly on my 85'. Got the boxes switched(it's a b!tch to do I might add /forums/images/graemlins/mad.gif) just to find out the fittings weren't the same when I wen't to install the hoses, tried to take a shortcut and get an earlier hose but the pumps are also different. When I was done I had taken a loss on a non returnable steering box, another 80's box, new pump (ruined the old one) an all new hoses. Man... I could have really used CK5's knowledge, damnit! /forums/images/graemlins/smile.gif. Anyway don't make the same mistake, make sure the fittings are the same and don't just look at the exterior of the boxes because they are identical besides the fittings.

    If you can make the hose work (return fitting angle is only difference I know of, besides the mounting studs) you can swap the old fitting on the pump into the new pump, or vise versa.

    Have a 1974 PS pump on my truck, with an '81 steering box, and some lines I had laying around that happened to have close to the right bends in them.

    Hmm, well it doesn't matter now because I replaced everything allready but I kind of destroyed the fittings when trying to get the hose out. It was an easy decision to just get a new pump though because My old box leaked so bad that it would run dry every couple of hundred miles and I knew that that wasn't easy on the pump and I wanted to not have to mess with it for a while anyway.
