After a close encounter with the edge of my garage door, I need a replacement cover for my outside passenger mirror. Auto part prices being what they are, I found a relatively inexpensive Internet source. The part arrived, with the correct part code attached, and it’s the right shape and color, but the fasteners inside don’t match my old cover at all! I believe I have the right model year (2018), what’s going on?
