1967 Formuls S 383 ?? Factory upgrade?

Auto or manual. Easy way to bust him, as I believe there was only 1 383 auto convertible Barracuda produced in 1967, and I believe it was the triple blue car that a lady inherited from her late husband. She brought it here to sell a number of years ago, and although I really wanted it, the $12k asking price was a little more than I had to spend. Nice lady tho, she also inherited a 383 notch, and another convertible she didn’t even know he had. That was some pretty stout examples, and very good hiding on his part!
