Hey Woog, Those are the same mirrors that came on my '66 C10 longbed from the factory. According to the, "Chevrolet Automobile Sales Order", in the glove box of my truck, they are listed as, Jr. West Coast Mirrors, on the list of my trucks accessories. On the, "Service Parts Identification" decal on the back of the glove box lid, they are listed as, RV Jr. Mirrors RH & LH, Option No. D29BA.
