I agree with Don so long as we are referring to the VIN tag. Is there any chance the tag you mentioned is a trim tag? The reason I ask is because replacement trim tags appear to be available from Trimtags.com.
I bought replacement rivets from them years ago for both vin and trim tags. They were really good to deal with.

If it is a special (SS, Z28 etc) car I would not do it. Experts over on Team Camaro can spot a repop Trim tag and will out you in an epic dogpile thread. LOL...
