IMPORTANT NOTES FOR THIS INSTALLATION:
1) Use the 16304 add-on kit with the 16100 universal kit. Read pages 1-3 of the 16100 instruction for general
information.
2) The mounting holes for row 3 go through the inside of the bed sill. Make sure it lines up correctly. Drill through
the bed and the top of the frame on both sides. For the Row 4 passenger side attachment, drill through the bed
and top of the frame as well.
3) The rear rail on the passenger side is secured directly to the frame with 3" carriage bolts provided in the 16304 kit.
For the row 3 attachment, a tube spacer should be placed inside the bed sill on top of the frame and under the
bottom of the bed. Line up the spacer with the drilled hole before inserting the carriage bolt. Repeat for both
sides. See FIG. 1 below.
