The car in question was a 68 ram air convertible. It had 900 miles on the car. It was at Royal Pontiac and was soon to acquire the bobcat package but at test time it was just as it had left the assemble line.
Maybe that was bobcat pins tripping that had already been added.?
As I study the image more....it already has a royal bobcat badge and a black out tail panel. The pin striped probably added as well.
In this image it show what comes standard on each model. Here is shows the 350 HO comes standard with the stripes.
