12. Align the holes on the template (provided with the gooseneck hitch) with the holes for the rear cross member
previously drilled through the bed. Be sure that the template is properly oriented toward the front of the vehicle See
Figure 10. Center punch the holes that will be used to cut the opening in the bed. If the vehicle is equipped with a
bed liner, a section of the bed liner must be cut away so that the gooseneck platform can contact the bed
corrugations.
