This article from an old monthly GM document, talks about a way around the problem of worn bores in a spindle. It involves stretching a standard bushing with a .010" kingpin to give the bushing a snug fit in the spindle.
I have broken the photo up into multiple images that are now readable. If you look at them in order from left to right, you can see the whole article.
