I asked this on the electrical section, but since I'm in a bind and a hurry, thought I'd run it by this group, too. I've got the original 6v blower motor that came in a box that has the complete old heater box. Got a new core and 12v motor, can't get the darn squirrel cage off the 6v shaft, so I either have to put it back in with the 6v motor (PO says it still worked- he had it boxed up to sell to a guy who never called back), or ruin it and cut the shaft to put the new 12v motor in. I ordered a voltage resistor from classic parts, but it won't be here till Tuesday. Bad weather coming Sunday night, no garage to work in, so I'm doing this today and tomorrow. NAPA says they have something they sell for distributors that is a 12-6v reducer. Anybody know if this type of reducer will work on these blower motors, or should I just put in the 12v and waste the 6v shaft as collateral? Thanks, guys.
