Black Plastic Part ⚽️ NO CLUE WHAT IT IS

According to Karrot Ai… This is a black plastic part for a car's side mirror assembly. It has the numbers 2-4 and 142841 1651 molded into it. This piece is part of a mirror housing. It came to me in a box of electronics. So i thought it was part of a computer set up? 🤷🏻‍♂️ I’m skeptical that it’s a car part. It’s about 10 inches long and a couple inches wide
