I have a 68 with a 302-2v. It has been "restored" previously. My question is: What color blue did Mercury use in 1968? Our 68 Mustang has the darker Corporate blue, but the Cougar is a lighter blue. Is the lighter correct, or did previous owner somewhere get it wrong? Also, the "Powered by Ford" on the valve covers is painted silver/grey. Is this correct? Any and all help appreciated.
