Most small centers bolt on with 3 screws, so most mopar wheels will have the 3 small holes in the center. Cop car rims usually had NO small holes as they used a pop on center hub cab, but of the 3 sets that I have had, a few had the 3 holes as well. The wheels with 5 little holes inbetween the big ones are common and maybe they went to 5 for some other reason.?
