Use the 1/8” rivet supplied in kit, for aligning the bracket with the hole in the vehicle, then line the brackets to run parallel with the edge of the “B” pillar hold in place and center punch through nuts on bracket. (See figure 5)

CDC will not be responsible for any damage that may occur if this step was not taken.
