This is way the factory did things back in the day and as someone who has been collecting hubcaps over 40 years I can tell you this is common. Just want to make sure those of you who like to nit pick are aware of this. They may fit other years, makes and models but you will have to do your own research. You must do your own research to be sure this is correct for your application. Compatibility list is only a guide of vehicles of this era and does not guarantee fitment.
As with all vintage hubcaps these may or may not contain dings, dents, scuffs, scratches, scrapes, bends, missing paint or parts, chipped paint, cracks, rust, pits, fade, wear, stains etc.. Therefore they are not perfect. Buyers are responsible to do their own research to make sure item is correct for their application. Please be advised if you are concerned about defects it is recommended that you view this listing on an a full size computer. Hand held devices do not have a large enough screen to view in detail.
