...am I an authority. I'm sure you've forgotten more than I will ever
know about hot rods and autos. When I turn the key, the ignition starts,
if not, I call AAA.

However, when I looked for the appropriate emblems, this is what I found:

1940 Ford Emblem
https://www.google.com/search?q=1940+Ford+emblem&ie=utf-8&oe=utf-8

1951 Ford Emblem
https://www.google.com/search?q=1951+Ford+Emblem&ie=utf-8&oe=utf-8

Google appears to be the authority you may want to question.
