I haven't done it since I installed the 302 grille, however I did do mods to that grille on the far left and right side with my dremel cutting tool that makes me believe it would be easy to do. After cutting out the fog light opening, Ford make very small drill holes around the opening and then used some fine steel wire to wrap the edges of the wire mesh onto the grille. If I remember properly I'd say they tied it down in this fashion in either 6 or 8 points around the circle of the fog light opening. I can get a close up pic off my grille is needed, PM me.
