Anyone knows the part number of this one?
 

Hi there! When I tried to remove the front bumper to replace the AKL module of my left headlight, I found the nut (in blue circle) was damaged, so I need to replace the nut so that I can fix the bumper onto it. Does anyone know how to replace the nut and the part number of the one circled in red? More over, which nut should I replace it? Can I just buy a normal 4.8-8 with part number 07129901655 nut to replace it? Thanks for help!
