Where are you getting your Tops?

Is it possible to install a glass rear window in a ‘65 Dart convertible? I’d love to have one in mine. It still looks good but it’s just a matter of time before it looks bad, no matter how careful I am.
I saw a 66 valiant with a custom made back glass window in it. It was nowhere near the size of the plastic window, though.

Had a custom well made so that it would fit right when unzipped. Also, not sure if there were well drain issues in it or not. I didn't ask the owner.
