Yesterday I was at the True Value Hardware store in Prescott, AZ. and found that they have a good selection of the caps that match the ones on the otherside of my Scamp
. They have them in White, Off White, Buff, and Black. I did buy a few and made sure that they were the correct size. They may have been a bit more expensive than what the factory sells, but I don't have to wait for delievery.
