You didn’t say what 270 model this is or whether it was an automatic or 4 speed so let’s assume it is a 2 dr hardtop. According to info I have (thanks Ulf 65dartcharger) there were 2819 270 2 door hardtops shipped. Out of those there were 287 equipped with the automatic and 271 with a 4 speed with the Charger 273/235 (Commando was the Plymouth name). There is no breakdown as to engine for AC, PB. and PS other than the total number for all 270 2 door hardtops. AC was 254; PB - 85; PS - 914. Hope this helps!
