1966 Dart Convertible 273 HiPo Very Rare Mauve Color Garage Find

Thank you for some info on production numbers. I looked and could not find data that broke anything out.
Were there only 431 model 270 convertibles with the hp 273 or was the number of 431 for all 270 models (hardtop and convertible) with the 273 hp?
I would love to see if there is any break down as far as color and convertible. This has to be a pretty rare combination.
Thanks again for your help
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.
