1968-72 Chevrolet C10 Horn Button Assembly

When I bought the 1968 Chevy C10, the previous owner had wired up a new horn to a button he installed where the choke was supposed to be in the dash. I wanted to get the horn working on the steering wheel. In the box of parts he gave me, I found an assortment of stuff that seemed to go with a horn button (according to various diagrams I’d found). Here are the parts as well as what I took out of the steering wheel.

I tried many combinations from the limited info I was able to Google and what I now know are incorrect diagrams in the LMC Truck catalog. Eventually I posted on the 67-72chevytrucks.com forum asking for help. Turned out the metal cup was too short! After getting the proper one and making an extra layer of plastic spacers (see video) I was in business.

Since I had so much trouble finding useful information, I created a video that’ll hopefully make it easier for the next person who tries to do this.

The threads on the steering wheel shaft and nut were in rough shape since the first time I took it apart after buying the truck. It got worse and worse as I worked on things in the steering column, especially since I’d been taking it apart so many times trying to get the horn button assembled properly (turns out one of the parts I have is from a different year). The other day it finally got royally fucked. In order to drive it over to Earl’s place for a fix, I used this spring clamp and was firmly pushing down on the wheel with both hands to prevent it from coming off. It was the most stressful 3 mile drive of my life. Luckily it’s a pretty straight shot from my house without much traffic.

Don’t try this at home!

New Radio Antenna

This old radio antenna had to go. It had some rust at the bottom and I didn’t like the look of it. The antenna couldn’t go any shorter than shown here, but it seemed to work fine in this position.

The next picture is when the antenna was fully extended. Did people actually drive around like this? It would easily hit my garage door.

This new antenna is much shorter and I think it really cleans up the look.

New Dimmer Switch

I’ve never seen a dimmer (brights / high-beams) switch on the floor until I bought the 1968 Chevy C10. The old switch was rusty and ugly so I ordered a new one as well as a bezel for the hole in the carpet.

One of the bolts was extra rusty and stuck, so it stripped right away. After trying several other things, I drilled through the top of the bolt until the head popped off. Then I was able to remove the switch and used locking pliers to twist out the bolt.

I put a new pad on the brake pedal, which was also much harder than expected!

A huge box of parts arrived on Friday, so I’ll be making a lot of upgrades over the next two months.
