The second mounting point we mentioned earlier is here outside the car at the pivot shaft. Since all the components are hooked to a serious bracket assembly these two points are all that is needed to keep it secure. To lock down the pivot shaft, you have to install the provided hardware in the order shown rubber seal, spacer, and then the nut. Then we went back inside and tightened the bolt securing the system in place. Also the stock chrome escutcheons will slip right over the new pivot shafts.
