    I'm replacing the ball joints and having the knuckle machined.
    I have a 73 2 wheel drive steer box, do the box's interchange between the 1st and 2nd gen's?

    I believe they do. You just have to watch out for newer trucks like above 89 some of the steering boxes are metric fittings.?
    I looked at my steering box and walked around the junkyard, found a 2wd version that looked the same out of a 77 or 79 chevy truck. It swapped right in, the only thing that was not the same was the rag joint.
    The rag joint diameter where it bolts onto the splines of the steering box are bigger for the 4wd and smaller on a 2wd box. Be sure you grab a 2wd rag joint with the steering box so everything bolts right up.

    I have the pump and lines to go with the box, looks like I need to get a rag joint now. Should be easy enough to get one.

    Pull the sector shafts and compare. Might be able to just swap out the sector from one box to the other.

    They interchange, like said above. Mines off a 76.
