Convertible Duster/Demon?

Hi...newbie here,
I've always wondered what a Duster might have looked like as a convertible?
I think they would have rocked! Some day I would like to create a Duster convertible if I had a second car to try it on. In the mean time I took a Johnny Lighting car and removed the roof and made a quick rag-top. You will have to visit my site on here to view it, the file pic won't load on this thread.

Has anyone ever seen a real convertible Duster/Demon before, has it been done before?
Thanks for reading this.

BTW: What do you peoples think of my real 74 Duster paint job?...some days I like it, some days I don't...Opinons welcome good or bad.
