Went to the Michigan Secretary of State, explained the situation, and was told I need to apply for a duplicate VIN tag. Its a tag with the original VIN number on it. I filled out the form, paid my $10. It will be a sticker that I believe is to be placed on the door. Its not the same as having the original dash tag, but should be additional assurance to potential buyers that everything is legit with the car. I have decided against getting one of the reproduction dash tags because I question whether its legal to install one. And even if it is legal, if after it were installed, it didn't look 100% factory installed, it would create additional problems trying to sell.
