I thought Julius' RR was a '68.

"Omaha Orange" started life as a fleet color "safety orange" and was used by many automobile & truck manufacturers for DOT vehicles and other state & federal agencies. Its popularity on some muscle cars namely California Road Runners, Barracudas, & Bengal Chagers led Chrysler to market a similar hue (EK2) with gold metallic in it as "Vitamin C" for the Plymouths and "Go Mango" for the Dodges starting in the spring of '69.
