A-bodies with Sunroofs

Here is my 1972 Duster with the factory sunroof. I would like to know if anyone else has one. I have only seen one on the internet. It was a Petty blue one with a white sunroof. Just for your information in 1972 this Duster was fender tag coded as a convertible. Plymouth's advertisement says with this option you get the open top while still preserving the solI'd top.
When open most of the roof is open unlike a sunroof that only opens for the front driver and front passenger area.
