I'm loooking for center caps that will fit over the exposed metal center parts of the rims of 15" turbines on an s/e. I don't want to use the bowling ball covers, and the caps I've seen on ebay don't fit turbine rims. I have pontiac logoed caps from the early 80's that came with the car which I glue on now, but after 20 years of use, the teeth of the caps are all breaking off, and there's not much left to glue them on with anymore.

Any ideas are appreciated! Thanks!
