1975 Pontiac G.A. Blower Motor Plastic Wheel
 

The plastic cage attached to my blower motor to heat or cool the car is broken and very noisy. Is there a part number and perhaps a way to purchase it?

Yes go to ANY parts store & get one, there all still available. About $ 35.00.

Just for the heck of it I went to 3 different parts store websites and all 3 list the same wheel for about $13.00. But, here's the kicker. All the wheels are metal and all are listed for non A/C cars. Two sites even had clockwise and counter-clockwise rotating wheels.
But, that is assuming that G.A. stands for Grand Am.
