No probs, it was pretty much only the front wings, bonnet and other front items that changed between the Phase1 and Phase2.
Only difference on the lights was on the Phase1 the uppers where smoked - indicator and reverse light - and on the Phase2 the uppers where clear not unlike ///M3 style lights.
Lot people go over to Phase2 rears as they are classy and give a clean look to the rear.
