<VV> air conditioning blower

[J Ernest Threlkeld]

I'm repairing a 1966 Monza coupe with GM factory air.  Someone has taken out
the original air blower motor, mounted in the trunk, and replaced it with
I-don't-know-what.  Is this the same motor as the heater's?  Is it a
squirrel cage motor?  Would the original motor be impossible to find?  Is
there anything else GM that might substitute?  Thanks in advance!  -J Ernest
