I bought the Beswick version before knowing the Dyno Don version would be coming (really, I should have assumed that one would happen). So when it came out, I bought it and swapped the paperwork, boxes, and parts around to create one opened but sealed inside Beswick kit, and a Dyno Don kit with opened parts bags. I was able to sell the Beswick kit and get back what I'd paid for it.
That's not one of his notable cars, as he only had it about three or four months and wasn't allowed to work on it to any extent. He gave it back to Lincoln-Mercury because he could get more appearance money racing his Pontiacs, which was pretty much the case until the first phase of his racing career ended prior to the 1972 season.
