The mounting holes on my new 2018 Plus match these parts, however there are a couple of uneven bare electrical connections protruding from the underside of the part (not shown in a few pics for better overview). I can't mount them on my metal frame without creating a short and they don't lay flat. A reviewer on YouTube shows a thick double-sided tape mount that looks like it might work. Please note that mounting screws are not included. So you have to drive to your local hardware store and also guess the correct length and diameter of the screw.
