That's so cool:) back when you COULD race and not get a ticket.
So I talked with my old man this morning, and while the similarities are very close, it's looking more likely like yours may just be a different car. He corrected my information, and told me he was probably the 3rd or 4th owner of his car. And he bought it from a man named Brian Rush, who had a custom California style 'tuck and roll' interior installed. I dont know what that would look like, but your Formula S appears to have the stock interior, is that correct?
Additionally , his Barracuda had fender well exit headers, which yours looks like it has stock manifolds.
Anyways, Perhaps you and my father can swap car stories, his name is John Russell, his cell phone is 941-932-5887
