- remove 4 rubber covers and 4 T25 Torx screws located under the tailgate middle. Leave the 2 screws 1 at each end.
- standing behind with tailgate closed pull the spoiler towards you. Start from one corner. It's a little tight don't worry it will not break if you hear a pop it's the white clips disconnecting.
-swap the 2 white clips and 4 spacer tabs. Make sure to take a photo for location because they need to go exactly same location on the M spoiler.
-to reinstall tailgate closed place the spoiler back on top, there are 5 tabs 2 on each side and 1 in the middle. Align tilt the spoiler up just a bit for the tabs go in them lower and push forward.
- open tailgate and put screws back and rubber covers.
(Use a magnet bit because screws can fall inside tailgate. when removing screws manually lower tailgate to prevent screws from falling inside tailgate but if they do don't panic just use a magnet screwdriver to reach it. )
Good luck took me 30 min.
