I have never seen any advertised. You will probably have to have yours chromed.
I have a 56 Vette that I had almost everything except the frame and engine block chromed. I now regret it. The older I get, the better I like the pure factory look. AND, I DO NOT LIKE ORIGINAL CHROME PARTS THAT HAVE BEEN PAINTED BODY COLOR, SUCH AS BUMPERS AND GRILL!
