There's an article on page 29 in the Nov 26 issue of Autoweek on John Fitch's 1966 "Fitch Phoenix", a car that he designed based on the Corvair that he planned to market. Bad timing, the National Traffic and Motor Safety Vehicle Act was signed a few months after he started taking deposits. GM then killed the Corvair, which also killed the Phoenix.
captainaudio, I'm guessing that you've seen, and perhaps even ridden in this vehicle, as it apparently made regular appearances at Lime Rock on race weekends.
