Sorry for posting in a zombie thread, but very nice work and excellent documentation. I'm doing the same thing with Skar, my 2020 Forester Sport, installing a Diamond 2 meter / 440 NMO mount antenna to the edge of the back hatch. Leased vehicle, so I have to be very stealth on the install, and be able to whip off all the accessories easily with no visible marks, cuts or holes.
