John, I came across one of these on a BN7 I purchased in San Luis Obispo, CA 10 years ago. The seller removed it to research it's origin. Later I was told that these were from a dealer in the LA area and were made by the dealership for the cars they sold...truth? myth?...don't know. Ben Cohen Tucson BN1, BN7, BJ8 and 2xAN5
