I just replaced my front bumper with a new one from ford becuase I slid into my wifes car last week. I pulled it off and replaced the bumper and ford bumper guard accessory. But I cant get the bumper to line up with the fender the plastic rivet holes wont line up. they are off about a 1/4 inch on both sides. Does anyone have any suggestions.. the only way i can get them to line up is to have my wife use her butt to push on the bumper, but once the rivet is in place it pulls right out. Help me please.
