Auto body repair & detailing: Bumper clip replacement help U.S. in JApan, late model cars, okinawa japan

Question
Hey Guys,
I am prior military living over here in Okinawa Japan and have a 2001 Harrier which is a Lexus 2001 rx300 in the states. When  
I got into a fenderbender i got rearended and sustained some damage to my rear bumper. Now the tabs that are on the sides of the bumper keep sliping out beause they are stripped. Any help on how to fix this or where to buy and or acquire these clips? Thanks for the help


Answer
I believe, even here in the states, that part is dealer only. I don't know of any after market supply house that carries these small body parts for late model cars. If you don't have a Lexus dealer nearby, check with the Toyota dealer, sometimes they will order Lexus parts.
