Maybe this has been covered before - If so I apologise in advance...

I have a 2001 WRX (low spoiler) and have just bought an original Sti big spoiler.

Before unbolting the little one I understand it has 4 fixings , the Sti version has 12.

Question is.......Is it just the case that I need to make a drilling template from the new spoiler offer it up to the original bootlid and get stuck in with Mr Black & Decker, or are there any other problems that I haven't forseen?.

If anyones done this, experienced problems or whatever, advice would be greatly received!!.

Thanks.

SB.
