The chrome deep-dish wheel cover for one of our rear duals was the wrong style, apparently installed by the dealer before they sold it. It was blocking the valvestems, so I pulled it off. Is there any easy way to find the correct one? I assume it was a one-size-fits-all aftermarket piece, rather than OEM. Does anyone know of an RV junkyard that might have one lying about?

This would be a good place to start.
