I'm pretty sure you can put the ball joints for the 85 in your control arms. I just swapped out the control arms altogether when I did my swap, but I've read about other guys just swapping ball joints. You will need to use the steering components from the 85 (centerlink, tie rods, etc), except I think you'll need to keep your stock pitman arm. When I did my swap with parts from an 89 Burb I used all the Burb steering parts except for the pitman arm because it was too big to fit my 68's steering box. Not sure about the rear; that's something I'm still trying to figure out myself. I'm thinking about having my axles drilled, but I don't know how much t would cost. Hope I've helped you out some.
