I know on my 68 I can reach the connector without pulling a fender or loosening the fender skirt. The connector is on the side of the blower motor closest to the engine. I wish I had a camera, I would take a picture of it. I feel for you if the spade is broken off or you have a bad motor because like Vikki said, you do have to pull the fender to replace it. If you do, you might want to replace your heater core while your at it.
