Just bought a 67 Galaxie Convertible. 390 car with 74,000 miles. I am missing the emblems off of each side at the rear quarter and the one on the driver's side on the trunk. Where can I get those? I also see where some were XLs. How do I tell if mine is a 500 or 500XL. I imagine it is just a 500. The car is light yellow with black top and interior. Thanks.
