Gents, looking for some help please. Just bought a 77 and the horn button and pieces are in a ziplock. Looks like one of the three plastic rivets is missing...but also the spring, contact, and small black piece are in the bag. Can anyone point me to a drawing that shows all the pieces and how they fit together. The steering wheel and all is assembled and works... just horn button not installed. I checked all the parts vendor sights and the drawings are all too general...don't show detail on the spring and contact for example. The guy I bought it from said locksmith, when taking out broken key, broke something plastic and inexpensive....thought he said a cover, could be the rivet though, ...and if so after buying a new set of rivets I may have all I need. Thanks for your help.

Do you have a straight column, or a tilt/tele one? The horn parts differ between the 2 columns.

If it's a tilt/tele, it was probably the Horn Contact Retainer that broke. This is a round white nylon piece, that has 5 flat, square, "fingers" spaced around it. With age, the nylon gets brittle and they far apart. There is a repro available in plastic, for about $8.00.

If one of the plastic rivets in the contact are broken, you'll probably need to replace it also.

I'll check to see what illustrations I may have, but even the GM Parts Book illustrations, are kind of vague. I don't recall if the parts book "green pages" illustration, even shows the Horn Contact Retainer!

The first two pages of this will show you how to take it apart.. just reverse.

If you are messing with the lower contact, here is how it installs.

Willcox, I think I have found my problem. Plastic revits are all that is missing or broken. Would you happen to have a close up photo of the assembled horn button stand? There is an isolator and I want to make sure it is in correct position before I assemble with new revits. Does your company sell the revits kit? Also need a set of three mounting screws. Thanks again.

Ok.. the rivets must be plastic... Give sales a call tomorrow and we can send them out on the cheap truck... 800-588-3883

Hope this helps.. Bottom stand, insualtor, metal plate, three eared plate... I'll double check this in the am.

Here is the retainer that is required to keep the c-clip in place and also insulates the big telescope spring from grounding on metal parts inside the steering column housing.

Here is a blowup from the AIM on a 1977 thru 1982 telescoping steering column, steering wheel, telescope and horn parts.

thanks Willcox for amazing quick reply...again. I will call tomorrow to order rivets and screws. Will also check back to forum for your validation of the stack order.

Jim thanks for your illustration too. Luckily I have not had to disassemble that far yet.

Correct... The bottom plate, the insulator, then the horn button retainer and then the upper eared plate.
