Anyone know howto replace the original roof spoiler with a S-line model? I've managed to source one S-line spoiler, but can't seem to figure out how it should be mounted.
From what I can see by looking at the current spoiler, it seems to be a fixed part of the boot lid - I atleast couldn't find any obvious seams anywhere. The S-line spoiler has three mounting points for screws on the bottom side, so clearly it needs to be mounted to something - but what and how?
Thanks in advance!

Just took a pic of what the S-line spoiler's bottomside looks like. Link here. Any ideas?
