New kingpin bolts are easy to find, and McMaster Carr should have new Oilite bushings for the kingpins. If there's a tiny bit of play, I promise you'll never notice it on the track. If you use flanged bushings, there's no need for thrust washers. If you decide you want them, McMaster has hardened thrust washers that are intended for use with radial needle thrust bearings, but work fine against bronze bushings. The n1ke spindles do have a little play after eight years of use, but the kart runs as well and as straight as it did when I designed and built it. TJ
