Could someone please list the part number of a commonly available (available at Autozone or other local store) 12 volt blower motor that works in the round (8 3/4" diameter core) firewall mounted heaters of the old trucks? The Filling Station lists a "universal" blower motor in their catalog, but they want $70 (plus shipping) for it and it's got to be the same model I could get locally for a lot less. These kind of restoration parts places are always trying to charge more for parts than they are really worth.

Thanks for any help.
