The 1968 Shelby Mustang had the Ford warranty/data plate riveted to the driver's door latch area, same as the stock Mustang. Prior Shelby Mustangs did not have the color tag at that location. The colors of the car were indicated by a letter code. Exterior and interior color codes were both found on this tag.
