Nelson,
This is my time frame , and I do remember the car, but never saw the construction of it . I have been in the automotive aftermarket for the past 55 years and we still have issues shipping no drive-train cars. I have attached some photos that I took of Paxton Products a few years ago. The building looks the same as the 60's when Andy, Joe and Vince were there doing their Paxton and Novi magic. I do remember going there when the were dyno testing for Indianapolis and hearing the Novi engines screaming at hi RPM.
