Chrome Metal Hub Covers Spider 4 3/4" Center Cap Kit.  How about this brand new pair of hub cap centers for your favorite Chevrolet? They fit the 4 3/4" lug pattern found on most of the older Chevy cars.The center bullet is almost 3" ID and sticks out about 3 1/2". It is metal. The chrome lug nut covers are plastic. Just remove your lug nuts, slip the dome on, tighten the lug nuts down and tap the chrome covers on. You're done! This listing is for 2 assemblies as shown. I listed these as a pair for the cars that have fender skirts, etc. Just buy 2 pair otherwise. I also have several styles of trim rings to accent these.
