Used factory installed vented fuel, or gas cap as installed on 1967-69 Mercury Cougar 1970 cars without California emissions. Also fits 1969-70 Shelby Mustang. In 1970 California required a non-vented fuel cap.
We stock these in limited quantities, and will have an intact paper gasket. Correct "VENTED" embossed and has the "S" stamped onto the center rivet. Price is established by demand, and these normally are only needed for very high level restorations or strict concours judging standards.
