Hope this helps someone. Owning a truck that is 15 years older than me sometimes gets me into trouble. By the time I ever even considered turning a wrench on a truck, this thing was 30 years old and so far off my radar that I wouldn't even look at one. That said, I'm flying by the seat of my pants and learning as I go along. Which brings me to the kingpins. How can a little box with a dozen little pieces of metal in it, dang near stop your heart when you open it? In my world everything is built with tolerances and bushings don't move and all that. I'm not equipped for this phenomenon of "floating bushings"! How much float is too much? Not enough? if you order the oversize kit, is it the bushing or the pin? In my instance it was the pin. Fine. If your axle hole is worn, that works great. My fresh dropped axle from Sid is machined back to factory specs, so that does not work for me. For the sake of not turning this into a rant, I will give the one piece of advice that is the most valuable. Don't order your small parts until all the big parts are back in your garage! Also, especially on old trucks, patience is a virtue! Too much reality TV out there, you can't really build your entire truck in six days! I mean, I guess you could...
