Can some one please tell me how to install a vy s pack spoiler on my vy please it is a genuine 1. The guy told me that on the underside of the boot there r 2 round circles drill in the centre of them and thats where the spoiler goes then he didnt tell me how to wire the tail light. I get the spoiler tommoz monday and wanna b able to put it straight on. Any help would be appreciated. Wat drill size would i need for the holes and would i need to put some kind of rust guard on the drilled holes ao i dont get rust?
