What’s the exact process to identify a real 66 Formula S Barracuda?

Some old pictures from 1976, restored in 1986, think the pictures of the car with the Goodyear Blue streak tires was taken in 1991, and those are original tires! Car now wears Coker repops and really makes the car pop...factory one as a spare yet.

See you still have the correct spare tire cover - it had the half C cut out for the larger wheel.....kinda hard to find those. Really nice car there !
