Found extra parts after fixing my car
Discovering extra pieces on the floor leaves people with no clue where they came from or if they are a critical component. Without a way to identify them, some simply put the parts in a cup holder and leave it at that. Others are left guessing whether leftover grease means a repair wasn't wiped off or if it comes from something else.
