I am re-attaching my steering box. When I took it off, I found these "Internal-External Combination Lock Washers" attached to the bolts. Does anyone know how many are supposed to be there and which side of the bolt (bolt head or nut) they need to be on? My concern is that those washers dig into the metal of the frame to provide the ground for the horn -- or I could be wrong on that. I've looked and cannot find an answer.
