In 72 you could order the V21, Performance Hood Treatment, the original owner of this Duster did just that....Also there were a few 340 Twisters built...they were for export only though, mainly to Canada. This decal was rolled up in the glove box upon delivery and installed by the original owner. The selling dealer was supposed to do this during prep, frustrated over it upon pickup he told them, "I'll just do it myself". This car was special ordered, check the code Y14 for sold car.........Dave
