here I have a decent parking light lens from the bumper of a 1967 GTX belvedere II satellite belvedere. I have a few of these lenses, and they are marked "R" or "L". please specify which side you need when ordering. they fit identically, so I have no idea why MA mopar cast them with these letters in. most people may not be aware of this. this is a stock photo, but all these lenses are about the same shape. light crazing and not hardly noticeable once mounted.
