I have a 1969 Barracuda 340-S convertible that I will be sending to the bodyman later this year. The factory paint is F5 green, and I can't seem to find any two cars that are supposed to be F5 that are the same color. I have noticed this with the F7 cars, but I never noticed the wide variation in F5 until I got my car. Does anybody have the correct formula for 1969 F5?
