On a similar vein, has anyone had experience with the roller bearing king pin replacement set? I read about it in one of the classic truck rags several months ago, now I can't find my copy. Would these work inf a 3/4T? Are they any good to begin with? Advice requested. Opinions accepted. Diatribes tolerated.
Thanks

Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
