Good evening all, I'm a new member coming over from the Jeep community. I picked up a '69 with a rim blow. The rubber tape and contacts are missing but it has a center horn button w pony/tri-bar in the middle of the foam pad that works. I haven't seen anywhere that there would be both. I'd like to get the rim going but wondering if I could keep the center button working too. It's wired to 2 of the screws behind the pad. Was this factory? Thanks!
