versa lock hub caps

Has anyone put Versa Lock hub caps on their Wildcat? Can they be used with the white Modulor wheels? It says they twist lock to stay on. Is there an adapter that comes with them? I'm putting on new tires and want to do away with those unsightly rusting center caps, and don't want to spend the money for new wheels. I'm going to paint the wheels blue, put on chrome trim rings and axle caps. I like the looks of these caps over the regulor snap on caps. Thanks, Tim
