. Why would anyone have ever "installed" a vinyl top on car #1
Sometime in the 60s Richard Petty experimented with a vinyl top,using the theory that the textured top would create small vortices over the car to help hold it down at speed. The idea didn't work at all & was quickly abandoned. Someone might have thought they could do it better than the pros & tried it. Remember, back then computers weren't all that prevelant & computer modeling almost non-existant, so they had to do real-world testing for some of these theories....
