Continental Orange is a great period color. Looks very nice, particularly with the chrome trim. Some relevant RoW information for 1976 can be found at

Next time I'm in Spokane I'll give you a ping...we usually travel over once or twice a year as my wife has lots of family in Spokane and Coeur d'Alene.
