Can someone explain to me why this NOS gas cap insert for a 67 GT500 is silver rather than gold? http://www.ebay.com/itm/NOS-1967-Mustang-Shelby-GT-500-Gas-Cap-Emblem-Insert-/270854679627?hash=item3f10326c4b&item=270854679627&pt=Vintage_Car_Truck_Parts_Accessories&vxp=mtr
Here's another one. http://www.ebay.com/itm/1967-MUSTANG-SHELBY-GT500-NOS-DELUXE-GAS-CAP-EMBLEM-SET-AUTOLITE-428PI-2X4-/320805542565?hash=item4ab1801aa5&item=320805542565&pt=Vintage_Car_Truck_Parts_Accessories&vxp=mtr I'm curious as the one on my car looks silver as well, and I need a new one. Were there ever silver ones on original cars??
