Does anyone know what the factory part number is for the heater blower motor on a 1967 hard top without AC?

Mine is trash, and I am unable to find any numbers on it.
When I go to the parts store or online, everyone tells me it is a single speed motor, but my current motor is a 2 speed. The ones that are supposed to be for my car have studs on both ends…but mine only has studs on one end. (the business end)

If I can not find the original motor then I may as well replace it with a brushless DC, 2 speed motor.
Brushless DC will draw less than 2 amps, but last forever..or at least as long as the roller bearings last.

 

It's a single speed motor used on 65 to 68 (without air on 67 and 68) heaters. The different speeds are controlled by the switch and a resistor group in the heater box. Try NPD 2007 pg 135, $44.95.
