I have been having noise in my front bumper. I determined it was the black plastic bump strip bolts were missing nuts. So I just went to drop my bumper. Came off alot faster and easier than i thought it would. That maybe due to the fact that my left mount had 2 bolts and my right mount had 3 bolts. There are suppose to be 4 bolts per side. Now looking at the back of the bumper there seems to be a black plastic piece that holds the bolts in place. This plastic piece is on the opposite side of the bumper reinforcement. The bolts that are hanging off the plastic piece seem to have bolts that have a strange shape head on them. Looks something like a star. My question is does anyone sell these bolts that snap into the plastic piece? Do I have to buy a new plastic piece with the 4 bolts already assembled?
