I saw a similar horn button done by a vendor at a race event at Laguna a couple of years ago. I wanted to do one and today, I finally put it together. I purchased a 3 prong wheel cap for $5.00 at the Part Heaven swap meet back in June. It had one of the 3 prongs broken off and was chrome with both overspray of black and gray primer. I broke the remaining 2 prongs off, wire brushed, and sanded it clean before painting it a satin black today.

I had also picked up a Momo horn button for $13.00 (7.99 and 5.00) shipping via evilbay.

I attached one to the other with 3M outdoor weater resistant double-sided tape. This stuff is super sticky and can easily handle the weight.

This is the end result. Yes, the horn works.

The gap is with 2 layers of tape.

Great job!

I have a Momo wheel and a brand new center cap... may have to give this a try.

Nice result Michael

Very nice, I did one last year and used epoxy and a washer to space out the horn button. I wish I had thought to use the duble side foam tape. It needs that extra 1/16 of an inch for it to work well. Nice job Badm.
