Hi Brad,
I got the pitman arm to fit by pushing back on the drag link and I was able to get it to fit. The pitman arm just looked to long to me but I was wrong. I mounted the steering box using a conversion plate from CPP that uses 2 of the existing holes and you have to drill 2 more holes in the frame. I bought a rebuilt 1969 steering box and pump for a C10. I'm replacing the steering box because I think it has a bad control valve or at least that's what A1Cardone the rebuiler said was the problem. The steering wheel turns left and right on it's own when you turn the wheel while it's in park. I'm hoping a different steering box will correct this problem. In hindsight, I would buy a kit with all the parts you need, Brothers has one on sale for $599.00,I spent more than that buying the parts separately. There is a slight angle of the box and steering column but I think that's okay. The front bumper bracket has to be shaved a little on the corner for it to fit because of the new box. I'll post an update when I get the new box installed next week hopefully.
