I had done this on the GE and just used the same walk-through on my GK:

Total time was about 10 minutes. I like this mod a lot because it keep sand, leaves and gunk from collecting on the rear wiper. Also, in the winter snow won't build up on it.

 

Interesting any pic of it done to 2015?

 

I did this over the weekend and so far I like it. There was a ton of sand sitting on the rear wiper before I did it, so it seemed like a good idea. The wiper at this angle is not very intrusive into the rear view either, which was my main concern.

Total time for this was 15 minutes, and 5 of those minutes were spent looking for a 10mm socket. The rear hatch cover pops right off; open the hatch and just start pulling on the bottom corner of the cover. There are clips all along the outside edges and 2 or 3 in the center. The steps are identical to the walk through for the GE.
