Kingpin replacement went well as well as I could planned. The original pins were worn about 0.015" on the ends and the bushings had about 0.020" wear from the pins. One bushing was completely worn through and the pin was in contact with the spindle.
Now that the wheels only have 1 degree of freedom, I am trying to cost effectively remove any steering play. From what I can tell most of play is coming at the ball joint between the pitman arm and the drag link. The ball is a little worn (less than 0.007") at the contact points. I tried to just tighten the threaded end piece, but that throws out the slot for the cotter pin.
I found a drag link repair kit, but it was labeled for 1/2 and 3/4 ton trucks. Are they a different the 1 tons, or will these work?

This should allow me to tighten it up a little more and keep the cotter pin lined up.
