I bought my nismo bumper off a 2003 coupe, and i am having fitment problems on my 2006. The main problem is when I am trying to put the screws in the two holes under each headlight, the holes on the bumper cannot fit over this plastic piece, creating an unsightly gap. How should I go about fitting this bumper? Creating larger holes on the bumper? How? Or should i remove those plastic things and fit something else into it?

I'll try to get pictures tomorrow, because I know it is very difficult to understand without actually seeing it.

P.S. My bumper is poly
