Anyone know the part number for the rubber stopper that stops the gas filler door from slamming shut? Mine suddenly disappeared after washing before I left for my deployment and I just remembered to ask about it. I'm guessing it's one of the pieces below, but I sure can't figure out which one. FYI, 97 2.8

Whalen Shift Machine, polished - Type II windscreen (non roll-hoops) - Bilstein HD shocks/struts
