First time i cut the tabs off the side of the grill and drilled new holes in the bumper 25mm infront of the standard omega one.
second attempt i had to bog/respray my holes and cut the four tabs off the bottom of the grill, so it doesnt have any tabs left on now,
dont know how this would go for you say, ive now also got the chrome strip from the calais on the bonnet, and this wedges the grill down tight
aint going nowhere. ill throw up another pic to show this soon.
anything else you'd like to know, pm me
