Hy Daniel-Rose, lots of questions, the .010" oversize pins are .010" larger in diameter than the standard size kingpin. I don't see how you could install the oversize kingpin in the axle without reaming the axle to allow the pin to fit into it. The bushings in the 1/2 tons are a slip in no ream setup, so if you bought an oversize kingpin kit it should include the correct size bushings for the oversize kingpins. If your truck passes your annual inspection, and doesn't have wandering or uneven tire wear issues, then I would consider it not to be broken, and therefore not require repair at this time, hope that helps.
