I just plugged in 3 different Bronco VINs and it didn't recognize any of them.
So I plugged in my 1968 Mustang VIN. It was recognized, but gave a lot of generic info, some wrong info (engine size) and some missing info (production plant).
I think we're better off sending Bronco people to the Bronco Ohio VIN decoder from years and years ago:
