On a recent pickup of a 2005 Screaming Yellow convertible I noticed two options that I’ve seen from time to time but they are never listed in any dealer brochures. First is the thin double pin strip that runs the length of the car from the top of the fender to the top of the rear quarter. The second is the color matched door protector strip in the middle of the door. The door bumper would be an easy dealer install but I can’t see them adding pinstriping with the accuracy that is needed in dealer setting. There was another yellow convertible in a yard with the same door strip. I’ve seen the door bumper on different Mustangs in three of four colors, but it’s a rare sighting.
