73 Blower Motor and Cage
I am going to work on the blower motor speed on the 73. Before I tear it apart I was wondering if someone had info on the motor and cage size.
Specifically what is the rotational direction ?? Autozone has both "standard and reverse rotation" in replacements using the C4 motor. And.. of course the squirrel cage is in different sizes and rotational direction for pitch of the blades for a C4 and I beleive a C3 replacement. Oh, while in there I will check the voltage drop and change the ground wire out as recommended. Thanks

I've done the C4 into C3 fan motor and cage replacement in the past without knowing any of the items that you've asked. I'm curious if I got lucky or if there is only one direction.
