I've found the origin of the mystery car part that fell onto my driveway last week. Follow these pictures, and you'll be able to solve the mystery yourself. Hint: it's not a flux capacitor. (By the way, another piece fell off over the weekend. I'll be showing it in a post soon.)
Clue #1: The piece.
Clue #2: The right side of the car, just in front of the rear tire.
Clue #3: The left side of the car, in front of rear tire. What's missing here?
The answer: the piece flipped over! It belongs on that rusted-out spot in front of the wheel.
