cracked fiberglass

Hi all,

I was in a hurry and backing up my 2006 chevy dually and accidently hit a place that caused the fiberglass to crack in the area around my rear wheel. Well I am going to try and hide it with some fender flares. I am looking for some really wide ones. I think the oem ones made by chevy are the widest. Don't know for sure though. Car is white so I am thinking about having them white to match. Either white or chrome will be fine for me but they have to be wide though. Any place online to buy oem ones or any additional info would be great. Thanks
