1966 Dart Convertible 273 HiPo Very Rare Mauve Color Garage Find

431 with the HP273. Hartops and convertibles are in one group with no further breakdown. Same with color. No further breakdown. I got that information in a written report on my 66 Dart from Galen Govier.
I did not realize the 273 hp was that rare. I know that the vast majority of 64 - 67 273 cars I have seen over the 40 years I have been into mopars have been 2 barrel cars but I had no idea they were that rare. With 431 total there sure cant be too many convertibles made like this.
