Unfortunately the dealer is the only place you're going to find them. Well, you MIGHT get lucky on ebay, but that's a longshot. The old Meriden badges don't fit...holes for the screws aren't spaced the same.
I found a new pair of eyebrow badges on Ebay - $60. I think all badges list around $95? You might ask Bob at Palm Beach Triumph for a better price - (800) 992-1511.
