I have scuffed up the lower black portion of my front bumper pretty bad on one side. It is the black part that juts out a bit just in front of the wheel. It appears to be one piece that goes from one side to the other. It is part number 17A989 on the attached diagram. What I want to know is how difficult it is to replace. Also, there is painted portion at the bottom. Is the painted part a separate piece or will I have to have that section painted onto the part I need? If it is two separate pieces, I would assume it is an easy fix. Finally, are there any screws, clips, etc. I need to also order?
