i had the same problem some guy hit me from behind and the thing was f@ed up. i got it repainted and the said it was the best they could mount it but it was still i lil droopy. this is the way i fixed it. make sure to straighten out the top lip of the rear fender. then there should be a plastic clip where the screw goes in to hold the bumper in place. well i just used a wider screw and forced it in there and it lined up perfectly. good luck, hope i helped
