This is a new one on me, convertible???

Exert from 'Barracuda Unlocked': Due to Plymouth' lack of show cars, a design study was preformed that year and a few models received the "Landua Canopy" treatment. the goal was to emulate the simulated Landua roof treatment from the 163 Chrysler New Yorker. A 1964 Satellite II and the Barracuda was chosen to get the alteration. Design studio assistant manager David Cummings directed the transformation on a base model Barracuda where the sheet metal shop cut the roof section out to make way for the soft top. A windshield surrounding structure and trim from a valiant convertible was used and the paint shop made the repairs once the metal shop finished. It really was a stunning design that was minimal effort towards creating a show car. It was determined that the roof line would have to be lowered to make a real show quality show car, and since there was little time to retool the entire structure, the concept ended there, while Satellite II went on tour. The car was intended to be fitted the coming Formula S package and if the roof were engineered to be feasible, this version of the Barracuda may have found its way into production. The Barracuda concept car itself actually survived as did the Satellite II. It was thought the cars were destroyed as was the practice at the time. The barracuda's authenticity was verified by David Cummings, and it's since been sold a few times, but restored to its original (almost) show car glory. There were reports that a Dodge A- 100 van also received the Landua treatment, but no supporting documents or photos have been found. Yet.
One of the raret options was the vinyl top, seen on 1965 and 1966 model years.
