Rear inner bumper stainless still mounting hardware. This set includes four stainless steel bolts, washers and nuts. It also includes four steel retainer rings. These are very often badly rusted and can be hard to find in good condition. Since these pieces are stainless steel, they will prevent any further rust issues. The rear inner bumper attaches with eight bolts so you will need to order two sets if you're replacing all eight bolts.
