1940 Ford Car Stainless Steel Hub Cap. Here is are brand new Ford Deluxe hub caps for your favorite ride. The digital camera can't show how nice the polished surface is. Stainless steel so no worries there. They are about 9 5/8" outside diameter. YOUR WHEELS MUST HAVE THE 5 SPRING CLIPS JUST OUTSIDE THE LUG NUTS FOR THESE TO WORK. Add some class to your car hauler? Can you picture these and a set of trim rings (I sell them too!) on red wheels? I can. I think these are nicer than the originals. They are Ford Motor Company authorized reproductions.
