70's Duster Convertible

Ive looked at my 71 Dusters roof lines in the back and side quaters, I think theres enough room in the rear speaker deck and trunk to make a Duster convertible fold away, it will take some tweeking of the top Swinger convertible frame to make it work and the soft top need to look just like the hard top Duster when up and installed keeping the Dstuer body lines the same as the hard top was orgially I saw a newer Charger that was made into a convertible so I'd say a Duster Convertible is highly possible. Does anyone know who in California is doing convertible conversions?
