I really am starting to hate getting parts here. I need a fricken VIN for a part for an engine that was produced between 4.5-07? And the parts monkey cops an attitude when I point this out? I've even brought in the VIN for brake lines and it STILL listed two different possible parts. I miss the good ole days of telling the parts guy what you want, and voila, there it is.
