273 Commando pistons

Never say never with Ma Mopar. The vehicles were thrown together back then and it could be possible for a 2 barrel long block to get dressed like a 4 barrel. Who knows why for sure. The workers would grab the next one from the line and do their thing. Just like my 66. It doesn't have bucket seat reinforcements for the floor pan. Someone goofed and they didn't install them or my car got a bench seat floor pan.
