I worked at Western Auto (Now closed Auto Parts and service chain in the Midwest) for 5 years after getting out of the USAF (93-98) while going back to school for an MBA. What I really liked was when people asked for starters, fuel pumps, alternators, motor mounts, etc for a small block Chevy. I'd ask year make and model, and they'd say, "They are all the same, just give me one." They'd come back half the time because guess what, not ALL small black Chevys took all the same parts.
Wow! Those cars do look exactly the same, don't they. LOL, I have had so many people ask me what year of a Camaro my 69 Barracuda Fastback was, I have lost count. BARRACUDA on the rear decklid panel, Barracuda on both fenders and PLYMOUTH on the front.
