Have the rear bumper off to replace the rub strip and noticed a little hole in the rear fillers it is in the middle parallel to where the gas fill is. Does something belong in this hole to join the two fillers together?
I just put mine back on yesterday, and yes there is a plastic piece that goes thru the holes to hold them together. I don't really know how to describe it, but it is similar to what holds the kick panel in place that covers the ecm........hope that helps!!
