These are extremely rare. Too bad they aren't OEM for my 68 Riv or I would have bought them already. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2450076118&category=33643
I didn't see these on thier site. Unfortunately, I am reduced to "collecting" Riviera Letters for my car. Too bad.
