I hate the "parts jockeys" at the advance near my house. Everyone in there thinks they know everything about cars....if they were so smart they would work in a shop as a mechanic and not sell parts.Anyways I needed a filter for the cutlass, the "genius" behind the counter looked it up and gave me the number, it looked familiar but thought it was wrong, it ended up being for a chevy 350. I went back to the counter and told him it was wrong. He said trust me dude, I'm a big oldsmobile guy this is the right filter. So i finally said I needed one for a 86 cutlass with a 307. Problem solved. If he only knew I build engines for a living.
