2010 Mazda 6 Part Numbers

Does anyone have or know how to access Mazda part numbers for my 2010 Mazda 6? Can I download a mazda parts manual? The dealer does not want to cooperate with my request for "Real" parts numbers and I do not want to pay dealer prices! I need the Mazda parts number for a rocker panel molding.....I am looking for a rocker panel molding for a 2010 Mazda 6. It is for the passenger side and fits below both the front and back passenger doors. I understand that the 2009 and the 2010 are the same. Do you have one or know where I can get one? The ideal color would be Sangria Red but would take any color.

Any help you can provide is greatly appreciated.
