Can't see your pics but the sports grill does have a slot on the bottom which the bumper goes into the old perspex one had a metal bracket. If the bumper on your car is pushed under the grill it might have snapped the bottom of the grill but if the bumper is pushed forward away from the grill you should just be able to tap it back in with your hand.Hey,
I have a 2009 Type-S (grill is original from factory), and some ******* seems that when parking he 'touched' my bumber. It seems that now the grill is not flush with the bumber see pics.
From your experience of replacing your grill, are you aware if there is an attachment between the bumber and the grill that makes the grill in place (flush with the bumber?) that maybe is now broken or not in place?
Can't see ya pics but hope this helps
