<VV> '65 Corvair heater "FAN" motor shaft keyed?

Mon Dec 8 16:10:28 EST 2014

Hi,

Looked at Autozone online listing and they don`t have one for our Corvairs, 
bull! 65 Belair AND 67 Cadallac DeVille both use the same aftermarket motor. 
The blower wheel for the Cady may be longer so take your old parts with you, 
always. Test your new part before you close everything up. Besure and check 
that the ground is clean.
