1966 dart commando 4 speed id

An 8 3/4 would be a good sign though. Take a look at the fender tag. It should have a 32 under the AB if it's an original 4bbl car. A 3 under the C would be correct for a 4 speed. Being a Dart, it would be a Charger 273 car. A front sway bar would be an option. It should also have an Inland shifter if it's original.
