There are thousands of classic Ford shops out there with what you need. Put Classic Ford in Google, and you will get many hits. I was looking for the "original" FORD letters or their replacements for a friend who owns an original 66 Road Car. I stumbled on this shop on the way to his house and went in to look at what he had. He has on display(and can get), just about every known Ford oval, and FORD letter size there is out there, as well as what it came off of. What is not known at this point is the exact shade of blue you want. I found that out when I got one for my car. It will be added sometime this summer when a few more clear coats get added. If you contact these guys they can help you out, or just search the net for someone close to you.
