Years ago we pulled in to a gas station in a tiny town in Oregon where you're not allowed to pump your own gas. The kid pumping the gas was convincing his girlfriend how he could always tell the exact year of a truck like mine because of my stock tail lights. The truck was wearing four 59 Caddy tail lights, but that didn't slow down or divert his story in the least! His girlfriend and I were both convinced they were stock by the time we left!
