Truck Hardware Gatorback 19"x24" Dually RAM Horizontal Mud Flaps - Rear With Brackets

The video was helpful but the kit comes with more hardware than the video shows. The written instructions show several additional steps to secure the mud flap to the wheel liner. I highly doubt the 4 bolts used in the video are adequate to secure the mud flaps without any inner wheel well anchoring.  They do look great and are definitely heavy duty.
