Hey Dan. What color are you after? I don't have any but bet some used ones are around somewhere. Or, it's kind of a long about way but SLS (in Germany) has them new for about 5 bucks I believe. Our US vendors may also have them readily available.
Ironically, I may be looking for one for an early style crank -- if anyone has one of those laying around... (unless Alfred, they were included?)...
