The wings have 4 bolts along the top, 1 behind the bumper at the front, 1 under a black cap(you will see it when u open door, below where top of wing ,meets a pillar), has 1 underneath bottom of wing and also 1 covered in selant behind the inner arch behind the side repeater.
I just bought a G60 which both front wings were rotten so they came off... :D
