i have had discussion with others on the fender striping on a 69 camaro. here is a link to one on ebay that has it marked on the car shipper that it came with the car. it list the fender striping for 15.30. so you could get it on any 69 camaro as a option including a non rs car, and also on a z28 ( correct )
