Regarding the exterior color breakdown, since there was no breakdown by color for 1969 Barracuda's, lets interpolate and make an educated guess based on factual information: there is a color breakdown for 1970 Barracudas. Although the body was restyled, the color, A4 Silver Poly, was still available. Based on the very low production of the A4 Silver Poly cars made for 1970 (approximately 0.8%), The estimated breakdown for 1969 Barracuda, A4 Silver color: 31,987 X 0.8 = less than 256.

Regarding the interior color breakdown, the available interior colors for 1969 did include a yellow/black option (option D6P, yellow interior with black carpet, instrument panel, steering wheel & headliner), but that exterior /interior color combination "was acceptable but not recommended" by the factory (see note at bottom of interior option photo below). So as a result, your Barracuda may have been
ordered new with that color combination, as opposed to typically manufactured that way.

Regarding the side stripe: The 1969 Barracuda 340 that came with the Code #A53 Formula S option had horizontal striping and Front fender 'Barracuda' only emblem.
