Eh? Where mate?
I did not have to drill anything, my FL lights fitted straight in with no modifications at all.
On the boot lid for the inner rear lights (reverse lights) to bolt on correctly. I had to drill 2 holes on both the o/s and n/s and pull out the existing plastic plug type connector on the boot lid for the push type pin (circled red in pics)
The space between the two fixing points on the edge of the boot lid are vastly different (between the blue lines in pics).
The 3 threaded studs on the bottom of the pre-facelift and facelift lens's are the same but the position for the top bolt on the pre-facelift is used for the facelift spoiler with the facelift lens having a hole closer to the 3 threaded studs.
There was no other way to bolt on the facelift lenses to my pre-facelift MK9 using ALL of the fixing points.
You also need another 2 5mm nuts to tighten down all 6 studs on the facelift rear spoiler as the pre-facelift spoiler (third brake light) is only fixed down with 4 5mm nuts so you are 2 5mm nuts short from what you have left after removing all of the pre-facelift rear lights and spoiler.
