Even the adapter bolts right on. A 2nd adapter (seen just above the motor) bolts to the adapter now on the motor.

The original heater was just a single speed; I wanted at least a 2 speed. To accomplish this I am adding the resistor from a junk housing to the heater box.

I will swap out the 54 Dodge heater switch I was going to use to one from a pre-65 Valiant or maybe from an early van that Jerry
@sgrip65 gave to me at the Nationals - it will be a match for the rest of the lower knobs plus a 65 heater harness mounts into both the switch and resister - win win!
