Or sometimes you get these idiots that "know exactly what they're talking about" and still give you the wrong parts! This one place where I got most of my parts for my old car, did this to me twice! Complete exhaust system, dude swore up and down it was the correct one, NOPE! (ended up bringing the car and exhaust to a shop, as impact wrench was needed, and I had none, or any friends with some, was new to town then) Luckily the auto shop just did a clean swap for the correct exhaust setup. The damn shop did it again to me with new brake pads! Nothing worse than getting your car ripped apart, and then finding out you've been given the wrong parts! (only had single vehicle at the time) So I had to manage to track a buddy down, and give me a lift, and I was late for work after the whole ordeal! Needless to say, I don't get my parts there anymore! Not worth the hassle, or the discount I got there!
