I got a good deal on a rechromed front bumper for my olds...I didnt realize when i ordered it that it was one that was not drilled for a bumper strip,,The bumper looks really good so i am going to go ahead and use it but need to find the right bumper cap bolts to fill the four holes that are in the bumper..Its either that are drill holes for the bumper strip and bumper bars that are vertial to the bumper,,,Any ideas
