You have to seperate the spoiler from the base plate. Its screwed and double sided tape that holds it down. Id heat it first, as it could crack. I was practically swinging off an old one when I fitted it to my Jordan, and something went on it, couldnt see it though. You can get those adjustable angle brackets for the spoiler but they are so over priced its not even funny. You probably can do it with some washers etc, but not too sure about how many etc.
