I've looked on various pages for patterns or dimensions on mounting patterns....but haven't found the info I'm looking for. I'm not a fan of the factory rear spoiler on my car...but don't want to have to get holes filled to change it. I don't mind if the new spoiler covers old holes and I have to drill new ones....I just don't want rubber plugs showing when I'm done....I like the Roush and Saleen style spoilers......what would be my options....thanks
