we offer a replacement plastic one in black that you need to paint however, it is not 100% dead on the same lacks the edge that the stock one has...
we do offer one in billet that is powder coated crinkled grey GN color that is dead on 100% the same and being metal will never pit or crack etc....sold it for years....we sell that one to other companies so when inquiring at where the metal one we market is by far the best...not often a repro part is superior to GMs original but this is.
not sure of the price since I am typing this from home, but its under $50...
