After having the steering column removed and the 3-speed linkage repaired, the contact device for the horn was lost. The mechanic doesn't know how he lost it or what the part looked like. The shop manual is not clear and I ordered the assembly below, but it doesn't fit (wrong year I guess). I'm looking for a clear horn assembly diagram and a source for the part. The contact piece is belown the steering wheel and you have to pull the wheel to get to it...must have some sort of metal contact to make the connection with the horn button.

Any advice is appreciated. Thx MDL
