i bought some new headlights for my astra but can't get them on the car. i have managed to get the grill off and take the three screws out for the lights but can't find how to lower the bumper. i have spoken to vauxhall but all they said was that there are two screws under the arch that i need to undo. i had a look but couldn't see any. after speaking to them again i was then told that there aren't any screws and that it should just unclip but there doesn't seem to be a clip as all it tried to do was break the bumper. does anyone have any step by step instuctions for it as i really don't want to break it especially as i have got my body kit attached to it????
