I have a '77 Buick Century Station Wagon. When purchased, it had the spoked hubcaps with the Buick emblem in the center. Someone jerryrigged the emblems with silicone or something and now they are all falling off. Does anyone have instructions on how these are supposed to attach? Or pictures of the inside so I can see how they are supposed to attach? It looks like the emblems have clips on the back of them, but there is nothing for them to attach to. I am attaching photos to better illustrate what I am talking about. I would appreciate any assistance! Neal
