When I got my 1954 Belair, in the trunk was a treasure box full of parts...wiper motor, 6volt radio (that works), dome lights, and parts for the horn ring. I have the horn ring, three plastic sleves, the springy thing and it's sleve, a plastic disc with three groves on the edge, and three screws...how the heck does it all go together? Thanks for any help. There is a spring too, but which side of the steering wheel does it fit, in the column (back side) or in the front???
