I have a 1967 Camaro with the N30 steering wheel that also has the two extra horn buttons on the upper spokes. This is not a column shif car, it is a floor shift automatic. The horn nor the turn signals work so I decided to repair them. After removing the center horn cap and rubber ring I found nothing else below them. So I pulled the steering wheel off to check further. There are still wires that still go to the two other horn buttons present. The only thing I found was the turn signal switch setting on top of the metal part that has the bearing in it that sets on the shaft. I am not really sure what it is called. Looks like a hub of sorts. I noticed that in the AIM UPC 12/C2 page 176 it shows parts #1 spring, #2 eyelet, #3 insulator, #6 spring, #7 cam assembly, #16 cover that I just simply do not have. I am not even sure that this is representative of a deluxe wheel setup. I have done several internet searches and found nothing so far. I had already bought a wheel horn parts kit from NPD part number C-2800-50C for the deluxe steering wheel. I know I need to buy a new turn signal switch assembly and a horn contact cancel cam. Like I mentioned earlier, UPC 12 / C2 shows #1 spring, #2 eyelet, #3 insulator, #6 spring, #16 cover. I'm sorta lost at this point. I really don't know what else might be needed to get things right. Any help from you will be greatly appreciated. Thanks for reading! JR
