So I found a SS steering wheel in a wreaking yard (9 months ago) and thought I took everything with it. Went to put it on and it seems something is missing. Service manual is no help. The canceling cam/horn wire connection on my column is the standard type, spring and wire going to the horn pad, but the connection to the horn button on the SS has to be different - no spring and wire. Also, is there something that goes between the cup with the screws and the flat plate? The plate seems to be cupped slightly and looks like the outer edge should go out but it touches the cup and steering wheel either way so the horn would blow. Seems there should be some insulator between them. Anybody have any clue?
