Cheers for the info thom89! Fitted up the plastic G60 arch to the new wings the other day, thankfully they fit up ok. I am a bit concerned as there is a huge gap between the underside of the previously cut back plastic and the new metal wing. I really want to stick with the G60 arches but I can see the gap filling with crap from the road and then the wings aren't gonna last to long. I did wonder about maybe cutting up a pair of GTi arches and grafting them on to fill the gap?
