I am looking for the brackets (2 of them with 2 holes each) that rivet to the fiberglass wheelwell, and straps (2) for the brackets, to hold the brass (not aluminum) radiator overflow tank (approx 1' long x 21/2" dia) used in a '69 Corvette [400hp w/air].  If you have any of these parts for sale, or know where I can locate or obtain them, please contact me at koditek@verizon.net.     

I believe that the 68 and 69 brass tanks are identical (and very rare), so that might help a little. 

Good Luck
Larry

Check with a rad shop, they sometimes use brass strapping when they recore a rad, they can make you a set, not orginal but to get you by. Also you can try a brass and copper fabricating shop,
