I know this is an old thread but I had to comment after reading your comment Beater of the Pack. My Dad was manager of a Schucks store in Seattle for about fifty years and knew so many parts by heart he hardly ever looked things up. Of course that was when vehicles were simpler too but you're right about the amount of knowledge that once resided behind the counter. He started working at the beginning with Erna Jorgensen and Harry Schuck, the founders.
