Question re: Horn Brush under Horn Button

[SoFla64]

So when i bought my 64, everthing for the horn was missing past the steering wheel. I've collected what I thought was everything I needed including 1 contact brush (because that is all the diagrams showed). I borrowed a puller from Pep Boys and pulled the wheel this weekend. I found the contact brush under the wheel was broken and replaced it. It was at this point that I realized that I needed two brushes. One for underneath the steering wheel and one underneath the horn button. The hole where the brush goes underneath the horn button is larger in diameter than the brushes they sell. Is there some sort of insulator or sleeve that goes in there or is there a wider brush I need to buy for that spot?

ok there is one brush in the turn signal switch which contacts the back side of the orignal steering wheel under the horn button there is only one spring i dont know about a two brush setup .look for a turn signal switch diagram that mey help you

The way mine looks is there is the one spring/brush underneath the wheel that contacts the surface of back plate then there is a hole that passes through the wheel and the plate has a "bump" on it. I believe another brush goes down through that hole. I found a picture from another site...the "thingy" that the arrow is pointing at

Well I have photographic proof that my steering wheel isn't the only one that has this. Anyone have an answer? Thanks

There should also be an "insulator" that fits into the hole BEFORE the brush goes in....it's supposed to hold the brush in place. It doesn't work all that well and gets broken/lost all the time. I don't know that anyone sells them anymore, but the Mustang steering wheel components are the same....I got all my horn "stuff" from the local club members.

Sofla64, on the turn signal switch there is a plastic post that contains a spring/brush assembly that touches the back of the steering wheel. Then there is a second spring/brush assembly that fits into the steering wheel (your green arrow) that touches the back of the horn ring. Both spring/brush assemblies are the same.

The four spoke steering wheel has a larger diameter brush.

Thanks guys...I replaced the brush behind the wheel with the one new one I had and I have the brush that was there.
The wire and spring are broken on the old brush but I found a click pen spring that will work perfect and I can solder a new wire to connect the top and bottom pieces of the brush. I just need to rig something to take the place of the insulator/sleeve since the hole is bigger (that's what he said... ) than the brush diameter.
Any creative ideas? perhaps I can cut a bic or papermate pen casing to length. ?

I was thinking the CAP of a ballpoint pen...they are about the same diameter.

My 64 is just like that too. I too used a spring from a pen and it works perfectly. Didn't bother replacing the little wire that connected the two plunger pieces as the spring creates the circuit anyway. I just soldered the two plunger pieces to the spring. For the insulating/guide sleeve I used a piece cut from a drinking straw. One of those sturdier red ones like you get with a slushie. It wanted to cause the contactor to hang up some so I coated the inside of it with silicone lube. No problems for two years now.
