arches - help needed!!

[match]

i have fitted 2 new front arches. and the passenger side 1 fits fine but the drivers side wing doesnt fit properly at the top it sits a little 2 far out where the wing meets the bottom of the windscreen and centre section of the bonnet.

any ideas on how i can make the b***ard fit properly??

[apples]

non genuine panels never fit properly! all i can suggest is to take a good look to see if there is any extra metal which can be ground off to bring it in tighter. if you cant see anything in the way hold a piece of wood against the edge and try knocking it into place with a few blows from a hammer, there is a good chance of damaging it this way but it can be easily filled and smoothed.
