Anyone ever try making a Duster a hardtop?

It would be damn fine for that back window to go down. I have a '67 Firebird, the curve in the rear window is not as sharp as our Dusters, but it is curved, and it does roll down.
If GM could do it, surely you can too!
A couple things to think through; the top seal would probably have to be fabricated, and also the front edge of the rear glass would need some type of seal where it goes against the door glass. Perhaps items from a Scamp or Swinger could be modified for that purpose.
I think it could be done, and it may not be that difficult given all of the other cars on the road with them already.

I do wish you would hurry up though, I'm starting to assemble my Duster and if you had this doable, now would be a great time for me to install!
