So I contacted Sewell parts to ask if the spindle grill will fit my 2011 570 and I got a response from them that there will be a gap where my headlight meets me bumper
The grill does not even touch the headlights. So i'd like a definitive answer as to if the 2013 spindle grill fits on the pre-2013 bumpers w/o modification. The question at hand is, are the grills the same size and the chrome pieces on each side of the grill matches up to the front bumper grill opening. HELP!!!

 

I'm going through 2008 to 2013 conversion. The new front grill will not fit the old bumpers. you will need to buy the new bumper and all the accessories under it.
