I have a 2009 Altima Coupe with a Stillen body kit. Yesterday, I noticed the part of the BUMPER where the red circle is started to come loose and upon further inspection, the mounting bracket itself is in pretty bad shape. I want to replace it but can't find the specific bracket for the car. If anyone here knows the NSN or part number or even WHERE I can find it I would appreciate the help! Thank you!

Looks like reference number 62674 on this IPB wis what you're looking for, which returns to the superceded part of 62221-ZX10A. Hope that helps!
