I used the staples that came with the OER kit I ordered instead of rivets to keep the “factory installed” look. The kit even supplied the drill bit for the staples. I then painted the staples with black paint to blend / hide them into the felt. If you use rivets, roll the door glass up and down to ensure none of them rub or scratch the glass. If you order replacement felt for the door glass guides, you will have some left over felt which you can then cut small circles out of and put on the head of each rivet as double protection against scratches. When you are marking the new felt strips for drilling, and when you are installing the felts to the door panels use a couple spring clamps, one on each end, to keep everything in place and lined up.
