I'd very much prefer to have to explain a "no plate" situation than try to justify a "wrong plate" in case of a minor fender bender or even a random stop by a cop who just wants to take a close look at an older vehicle. Back when I drove a restored 47 Mercury convertible in my college days, I got stopped all the time for a "vehicle inspection". Those guys loved the Offenhauser finned aluminum cylinder heads!
