i was driving on the freeway and a car infront hit something in the road and i ended up driving over it. it ripped off my rear bumper. i was wondering if anyone knows where i can buy replacement clips/fasteners and how to fix the damage. i know a real auto place is the answer, but i already got this new bumper from getting rear ended. i was hoping to make the damage less visible and ill be happy with that. i believe the damage is a crack and kind of bent? its on the very bottom.....thank you for the help
