I don't know what Wisconsin does, but no inspection in MN. And what cop short of a true old car/Mopar nut would even know about the rivets? I've never once had a cop even ask to look at my vin tag, or any other sort of inspection other than a burnt out bulb. Cops are usually pretty dumb when it comes to old cars and originality, I doubt some deputy who can barely wipe his nose even thinks about things like that.
