Hi Tom, welcome to the community!
Is the sunroof not glass, and painted the same color as the car and flush with the roof? Does your Pantera have a different cut down decklid? Do you know if it was once painted yellow?
If so, you may have purchased the Dellarosa Pantera which was for sale some time ago. It's a rare Pantera.
Post some picture for us to see, and good luck with it!
