65-66 factory racing stripes

Thats a good one. They differentiated cars on the track, like numbers did. You get 3 of the same model cars together in a pack and the different color stripes would seperate them to a fan or official. I thought they were all a dealer option, not called out on the build sheet, like 65 disc brakes.. 6 inch center paint stripe on centerline, 3/4 space and another 3/4 flanking paint stripe for a '65 but there were subtle differences as they were dealer painted.
