Yes one of my horn buttons finally popped off/broke and I was facing removing my steering wheel and figuring out a better mouse trap. Don't know if I did, but check it out--I glued a pair standard foam earplugs, cutting a slot to fit along the plastic tabs, and glued the button back into place. Seems to be the exact depth, rebounds after making contact, and so far has stayed in place, even in the Los Angeles sun. I used Permatex clear RTV silicone adhesive. Too simple to be true?
