Mike B.-Not sure about the reamer. I haven't taken the old kingpins out yet.

1/2 ton needs no reamer. larger than 1/2 ton I may have a reamer to suit.
I've also got some loctite 660 if you want to fix 1/2 ton bushings in the spindles, I feel this is an improvement over the stock full floating design.
