Fight on SC

The part that I'm refering to, goes under the steering shaft lock plate. A small copper cup and spring, I had some work done on the steering, and the mechanic lost the pin. So he wound the spring in a knot, and made the horn work.When the horn button cap is pushed, I did not realize why the spring was in a knot. And of course untied it,

I bought a replacement which is completely different , after cutting a half inch off the pin. I put the shaft lock plate in place,with the new unit. Connected the battery and found that the horn is constantly live.

I still have the original turn signal cancel cam, and I believe the part I bought works with a different style of cam. As shown on page 156 of Dr Rubuild's catalog. To fix it I would need to buy a new cancel cam, as well as a new lower horn contact plate. I would prefer to keep everything original, but I'm unable to find a picture or diagram. Of how the 1977 Vette left the factory.

Thank you in advance for any assistance

Today's post looks like it's referring to the contact in the turn signal switch, whereas the earlier post you linked to seems to be the contact in the steering wheel hub.

Same problem, different areas???

Yes it's the same issue, the new part does not work . Due to the reason I explained . The part I bought is shown on page 22, of the Zip catalog part number ZSC-35 $7.00. On page 156 of Dr Rebuilds catalog part K and part M, has the diagram where the cancel cam is completely different from mine. With a tube for the horn brush to go in to , and you lock in to place.

I have tried my best to explain the issue, it's the same problem . I will try to take a picture and perhaps that will help.

From the begining I called Zip products and explained what I neeed, they informed me I need a new horn brush. I looked at the part in their catalog, and stated" It does not look like the part I need". They assured me it would work, and explained the part had been changed over the years.

This is what I need from the 1977 shop manual, page 3B-64 to the right of the upper steering shaft. It goes in the turn signal switch unit, this part is not listed in any of the catalogs that I have.

Does anyone know where to find a replacement?

Does this picture help?


You didn't mention if you had a standard (non-adjustable) or a T&T column. I assume it is a T&T.

Why are you refering to Doc Rebuilds page 156 (1963-68 Std Strg Column) parts K and M, when you have a 1977?

I am confused, this is the first time I have heard of someone having an issue with a column, I had someone come in the showroom the other day with a 77 column and bought a ZSC-35. I don't think this was you but is it. That person did not really explain anything of what they needed, they just needed the horn contact which is what you are calling a brush. It has changed over the years, it used to come in the correct length and now it doesn't, it is a one size fits all makes. The Corvette needs to 3/4 of an inch long and you can cut it with a hacksaw, cutoff wheel, or I use just a pair if dykes and then grind it flat. The part that you are referring to in the picture that is in the turn signal switch is not available seperately. You have to purchase the entire turn signal switch to get it. If you would like you can call me and I will explain what needs to be done.
Thanks

A picture will help tremendously.

Let me rephrase this, first time this I have heard of a customer having an issue right now with a part not fitting his 77 column. These calls usually hit my desk and I have not had one yet.
Thanks

Noonie's picture number one, a copper cup to the right of the upper steering shaft . That's what I need, I used the term horn brush due to the fact, that Zip and Dr Rebuilt use it for that part.

Yes I have a T&T column.

That part comes with a new turn sig switch.

I have this one if you can get the horn brush out of it. $10 shipped in USA.

so here is a question. the plastic tube that the spring and rod slide into is broken on my so the black plastic retainer for the rod does not hold onto anything. Is that white plastic tube a separate piece that can be replaced?

Zip Corvettes

that is not the part that we call a horn contact and I am sure Dr. is not either. That part you are talking about is part of the Turn signal switch and is non-serviceable. The horn contact is the aluminum shaft that has to be cut down with a spring and a retainer that is used further up in the column.

I don't understand how the mechanic could lose that part. It does not just lift out of the switch. Must be a shoulder on the pin that retains it in the switch.
