Lose bumper help
 

Hi All

before I bought my car the dealer took off and resprayed the bumpers for me to get rid of 2 parking scuffs. I now find the rear bumper is lose at the wheel arch. It seems like one of the pins has popped out and lost the backing that holds it in.
Can anyone chuck up a link to where I can buy a replacement, I don't know what they are called so cant really search.

Thanks
Ade
