M-Performance F31 spoiler installation

[blackpanther]

Hi everybody,

Recently got a genuine M Performance Spoiler for F31.
I have a template how to drill the holes, but no more details, so not sure how to drill it properly. 
Tried to search for a video, but looks like everyone hates F31 (estate, avants, touring, kombi)   Only F30 videos all over.
Currently the spoiler is in the bodyshop to be painted as the car.

Hi,

do you still need help? I could send you the installation instructions.
