If the buzzing you are hearing is the starter turning in the bell housing, then yes, probably a bad bendix.
That is what kicks the gear on the front of the starter into the flywheel to crank the engine.
The resistor block on the firewall was back in the 60's I believe and was in place of the resistance wire all other manufacturers ran to the coil. It is there because after the motor starts, you don't want a full 12v to the coil. It will overheat and blow like a volcano. Ask me how I know this. LOL

The ballast resistor in old Mopars is in the ignition circuit.
