Not true. According to my 1938-1970 Chevrolet Truck Parts Catalog. 40 series '60-'62 fenders, have their own part numbers. Different from the 10- 30 series, & also different from the 50-80 series. Check out the Gallery, of this site, & you'll see the difference in the C10-30 trucks, compared to the C40- 80 trucks
