8. For 6300/630044 & 8339 use outer edges of the long slots in the rearward cross member as a template
to drill 5/8” diameter holes through the truck bed as shown in Figure 4. Not all holes can be drilled
from under the vehicle, but will be done later from inside the bed.
9. Align the holes on the template (provided with gooseneck hitch) with the hole previously drilled
through the bed. Be sure that the template is properly oriented toward the front of the vehicle. Center
punch the holes that will be use 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 hitch can contact the bed
corrugations.
WARNING The fuel tank and/or other vehicle components are located below some of the holes. A wood or metal shield must be
placed between the frame and the fuel tank to prevent puncturing the fuel tank when the drill breaks through the bed.

10. Drill 1/4” pilot holes (size will depend on width of blade in saber saw).
11. Cut out the truck bed. File edges as needed.
12. Install hitch into opening.
13. Using the hitch as a guide to drill the 5/8” diameter mounting holes through the forward cross member.
Also drill 5/8” diameter U-Bolt holes if installing a 6300 or 8339 gooseneck hitch.
14. Before installing the 5/8” carriage bolts through the hitch, the U-block shims (Part Number 5971) must
be placed between the hitch and the bed. These shims are necessary to prevent the bed corrugations
from collapsing when the bolts are tightened.
