You gotta love peoples "car knowledge"

There was a guy at Schucks (Checker/Kragen) who I'd constantly send on a wild goose chase. I'd ask for a chrome differential cover for a Ford 9" rear end about once every 6 months. He'd end up calling other stores, or dig out huge parts books to find it.

Sometimes he'd suggest some bs part would work, and I would then ask say..."Oh, whats next, a chrome diff cover for a Ford 9 inch?" He'd just stare at me.
