VIN Rivets

A friend of mine is thinking of buying 1965 Dart that is in pretty good shape. Owner removed the vin tag from the door pillar when car was repainted. Vin tag is now held in place with sheet metal screws. Checked vin tag using decoder and everything appears to be in order.
I know that in 1965 the vin tag was spot welded but how should this vin tag be attached to pillar post? Could rosette rivets be used or a strong adhesive?
