VIN database, or Pontiac registry?

I am looking for the 1979 Trans Am my dad bought my mother new. I have the original temp tag with the VIN. Any help in locating this car or information that would help me search for it would be greatly appreciated. I lost him to cancer in 2008 and I've always wondered about that car. It was the hottest car he ever bought and he had many different awesome rides. Thanks to anyone who can offer any guidance.
