My Trail Boss had lifter failure and when I got it back after three and a half weeks I found a nick/scratch on the driver door. Long story two attempts to fix it and it's not fixed satisfactory. So I'm taking it to the body shop of my choice and the dealership to a reimbursing me. My question is they forgot to put the plug back in the hole on the door shell. See picture. Can anyone tell me what it's called or where I can get one. Thanks in advance
