Finding these rare dealer installed items in VG used condition is like finding hens teeth ... with gold caps! I would buck up and buy the nice new repros from OPGI. I've pulled in 52 parts cars, maybe 4 had the right sight mirror, 3 were poor condition, 1 was maybe fair with typical moderate pitting found on the base. When OPGI finally did start selling them about 3 years ago (or more now), I ordered 18 from them at a discount and everyone of them shipped out that week! One went on my 64 CDV. Backing up 20 years USA Parts and others sold new repros, but for well over a decade no one sold them and the demand went thru the roof until OPGI began selling them. At this point perhaps USA, McVeys and others may have new ones.
