I guess you mean JC Whitney but I think that at one time JC Penney also sold auto parts.
Whitney, Penny...at this point, what difference does it make?
In the 60s Penneys had an auto service center, much like Wards and Sears at the time. They sold Bridgestone motorcyles, classmate of mine got a Bridgestone 50 there, rode it to junior high every day. At that time in Florida a 14 yo could drive a bike of 5 bhp, usually 60cc or less.
Amazingly, it looks as though J.C. Whitney will outlive JCPenney. And the former is best known for stuff like illuminated naked lady hood ornaments.
