Early A exhaust manifold questions

Interesting! According to my literature (and production figures provided by Ulf), the Charger 273 - sane as the Olymouth Commando - was available in 65 in any model EXCEPT the wagon - from 4 door sedan to the top of the like GT. When I get home I’ll post a breakdown for each model.
I needed to edit my post. According to the Galen option code book there is no 4 barrels listed for any Plymouth model other than the Barracuda. The 65 Plymouth sales info on the Hamtramck website lists the 273-4 available for the Valiant, all models except for the wagon.
