I'd like to get a new heater blower (aka fan wheel or squirrel cage) for my 68 Charger. Or at least the width, diameter and shaft diameter of one so I can try to match something up at the parts store. Any ideas?

Napa lists this one but it's a plastic POS and not even close to the right size: http://www.napaonline.com/MasterPages/NO...wer+Motor+Wheel
