So Im working on a 1929 Graham Paige. In other words I cant call around and get parts to fit the car. I just replaced the bushings in the kingpins and the welch plugs were destroyed on removal. The kingpins are roughly the same diameter as ford from 1928-48. Now does anyone know where I could get replacement welch plugs? I have called our local CARQUEST and Napa to no avail.
