So i got a jdm bumper with an authentic mugen grill and lip but the grill dosnt sit right. It sits high and pushes up my hood... The previous owner just double sided taped it. Are you supposed to shave and fit an authentic grill? Or is it made to sit perfect? I was gonna sand it untill i felt like sanding the inside to find the authentication stamp and found out it was real lol http://img.tapatalk.com/d/14/02/27/dedaqyju.jpg
