On my 2000 there was 3 holes on each side when I took off the spoiler. 2 were for the mounting bolts/nuts and the one was for the alignment dowel or whatever you want to call it. So if you move it back, you can use the alignment hole for the 1 bolt and only drill 1 new hole. Hope that makes sense.......BUT if you get plugs, you will need 6 plugs, not 4 like the 01+ CARS
