Greetings all, I know this is an older post. I stumbled on this as I was searching around. I figured I'd post my learnings to help the next fool who comes around. There is a tool called "Find My Font" That uses image reignition to try to match a picture of what you have. When I run that tool on the mustang lettering it comes back with "Clarendon Wide (Medium)" After checking this against my old eyes, it seems to be a pretty good match. I hope this helps.
