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

I think I ordered the Blue Streak tires through Summit
I looked at Coker and the only tires they show are a 3/8 inch wide blue side wall tires and no blue streaks and about $350.00 each. I would pay that if they were the blue streaks but a bit pricy for me with just a blue line. I'll spend it on a set of TTI's and a pair of slicks. As I tell my kids grandpa needs a new pair of slicks. lol.
