ah fair enough...
heres an idea of what i had to trim...
trimmed the mounting lugs on the top front of the bumper... these were trimmed to allow the bumper to sit in lign so its a good place to start...
then the edges around the front of the front wings needed trimming a bit, but thats it
the bumper did stick out a bit at either side, but when you screw it to the inner arches, they pull it in
