Octavia Mk3 Hatchback boot spoiler installation kit

Greetings fellow Octavia enthusiasts 🙂 

I have recently purchased a 2017 Octavia SE L 1.4 Tsi Hatch manual and absolutely love it! My last Octavia was an SE Estate 1.6 TDi estate and am loving the SE L spec.

I have purchased a genuine boot spoiler from Kopacec - https://www.kopacek.com/skoda/sale/octavia-iii-original-skoda-autoas-rear-trunk-spoiler-from-the-rs230-limited-edition-unpainted-2

I am going to get this color coded and professionally fitted, however the spoiler was delivered without any fitting kit or template guide etc. I emailed them and they said (quite abruptly) we dont supply them to prevent people trying to install them themselves on a drive or in a garage.

It looks like it will need 4 bolts and 2 bonded gaskets and have searched the internet and cannot find any info on where I could get hold of this to pass to the body shop (they may not need it but thought it would help)

Just wondered if anyone has any experience of fitting one of these and if they know of any info please ☺️

I have also got the Monte Carlo black lettering to go with the black badges to fit.
