I have a Thompson Products book. 1932-36; K30, K32, K33, K34 same. Bolt # 311, upper bushing # 2101, lower bushing # 2824. If you cannot find the bolt, a machinist should be able to make the bolt. The OD of the bushings may be standard. In that case press those in and ream to fit bolt. I had to do this on a 1912 car.
