For 1967, most of the Pontiac plants adopted a system where they placed coded information outside of the blue border area of the window sticker (as seen in the sample). The formatting of these codes varied from plant-to-plant. This is the easiest way to identify one of our window stickers (or an original) from other reproduction Pontiac window stickers. Ours have the correct codes printed outside the border, other reproductions do not. We pay attention to details.
