I redid the brakes on the car this week, and I decided to do the dual piston Impala setup while I was at it. When I asked for the parts, I asked for stock rear pads and rotors for an '04 Grand Prix GTP, and front pads and rotors for a 2006 Impala. He asked me what size motor was in the Impala (to put it in the computer), so I explained that they were going on the GP and they're all the same part number, but this guy just wasn't having it. He kept asking, not listening to a word I was saying about the part number, so finally I just said "pick one". Well, that guy doesn't like me too much anymore. I get that not everyone knows about cars, I certainly don't know much, but Jesus, that guy just refused to listen
