4. Remove the vent located behind the tire bracket. The factory weld nuts must be removed. Using the supplied M8x60 Bolt, remove the weld nut by threading the bolt in a few turns and bend the bolt up/down and side to side. The spot welds will easily break off the inside of the door. Reach inside the door and remove the nut from the bolt. BE CAREFUL NOT TO BEND THE BOLT TOO FAR, IT MAY BREAK! Repeat this step to remove the remaining 7 weld nuts. Refer to Figure 5.

5. Install the Panel Nuts as shown onto each of the Backer Plates. Install the completed Backer Plates into the hole in the door. Hold them in position while holding up the tire bracket and reinstalling the hardware removed in Step 3. [You will need a friend to help with this step]. Refer to Figures 6, 7, and 8.
