I bought the straps and grommets. but the metal bracket you placed behind the cutouts didn't come with those. Where did you get those, and what are the sizes? Thanks!
This is exactly what I did for my 2026 4Runner. Used the existing mounting clip and that 3D printed piece from Amazon. Works well, holds it solidly, and I don't have to worry about outside moisture or having it stick to a moving rear window. :)
