My bumper can be bufed and repainted and then reattached, nothin is broken on it. As for my hood OEM would be fine cus its not an aftermarket hood that was crunched. My lights were one piece JDM lights. My insurance company says that they put the car backl together just the way it was when it was in the accident. So to me that means that they would replace aftermarket parts. And the radiator of course would be OEM. The only thing I rewally want to upgrade are my lights b/c there werent giving me much light output, so I wanted to get some halo projectors from ebay or something.
