I am going to mount my spoiler on my Pearlie tomorrow, and had a couple of questions. If you look at the area where the bolts should come through, there seem to be cone shaped holes where the bolts might come through. Is this the mark for the hole to be drilled? I see three on each side, but the back 2 seem to be alined in the right area. What sized hole is needed? If you have done this, please let me know, or PM me with more information. Thanks in advance. I get more than a little nervous about drilling holes in my trunk lid - especially when they could be in the WRONG PLACE
