Which hub was actually designed for the 1959 Flightsweep tire? The 1959 site, under spotters tips shows the one with concentric circles, which more closely matches the hub caps of a 1958. In 1959 the hubcaps changed to the gear type center, which more closely match the Flightsweep hub with lines around the perimeter. I always thought that back then, every model year was completely restyled, but I am seeing many 1959's with both types of Flightsweep hubs. They are all attractive, I'm just wondering which is supposed to go with which year. Bill '59 Crown
