got the pics Bob - I'll put the heater ones up, and you hopefully have submitted truck pics to the editor for the gallery, that's a real nice 57
also, for posting pics in the forums, see the Manual linked in my sig line
you can reverse the motor rotation by temporarily switching the + and ground, if the motor has 2 wires from it, which would mean it's possible they are reversed - if one wire, it's getting ground via the case, so it'd have to be an internal switch, not likely if it's an unmolested original .... you can check it easily when you have it apart and the motor is separate
