The horn button mounting part that holds the actual horn button [ for the wood wheel or rosewood] 4 parts to it, three metal parts and an insulating gasket. the nylon rivets are all broken I need to know exactly where the insulating spacer goes, or in what order. Maybe someone has one laying around who could look at the order. The insulator goes either on the bottom or the top of the center piece. Also need the pin and spring. Much appreciated.
