Hi - hoping someone can help me. l'm not car savy at all! Something smacked into my driver side mirror while on the highway. I was able to grab the top piece of my mirror cover and snap it back in but can't figure out exactly what piece the bottom cover is. I have pictures of the missing section and the other side for reference. Not sure what's important: mirror is heated, no turn signals, and no driver assist. 2018 Subaru Impreza Hatchback (Limited). I did look at Subaru's website and typed my Vin in but it's showing me a diagram with more cover pieces then it looks like I need, I think it may be showing me the unit for a mirror with blinkers on it. If you're able to identify the part number I need, please help me!!!
