Pretty shit pic and kinda hard to see whats been done in it when you take the mud flap of you'll see where to cut back on the angle.
The mudflap a has been pushed back on angle as far as you can then the inner guard is basically
moulded till its smooth.
each car is probably slightly different and its a bit of moulding and see if it still hits thats what i did. you can do it with the wheel still on.
