As others have noted, the 69 Camaro Assembly Instruction Manual, pp. 474 - 475, under option Z28, illustrate the stripe locations and dimensions. Also, if you read the links Mark posted, it does a good job defining the width of the stripes. I have seen numerous Z’s with the rear RH trunk stripe ranging about 1/8” to 5/16” wider that the LH so that the “o” in the Camaro emblem fit inside the stripe. The pic of 69 Pace Car is an original car.
