Well, I know Phoenix cop cars were all tan and white in the late 60s up to the 80s I believe. But that alone doesn’t rule this car out. I don’t do Facebook so I can’t see all the pics. Is there a fender tag? I just doubt it being a cop car because it’s a 2 barrel 360. I owned a 76 Coronet wagon and a 75 4 door sedan that both had a certified speedos and a 318/360 2 barrel. They were part of a government fleet of car pool cars or something like that. I also had a 74 Coronet cop car with a 360 4 barrel that was a cop car and the fender tag proved it.
