installed plow, but found a small part that I have no clue where it goes.

Ok, when took headlight out, laying on the panel under the light was this part. I looked up the part # and its a bumper stop. No clue where this thing goes. I found the right side one laying in the same place, so I cant go by that side for reference. I'm assuming by the rubber piece that its a anti rattle item. Should I be concerned there in my pocket instead of my truck...lol
