tener installation instructions on the back page. Replace the
Base Assembly in the vehicle and fasten it to the floor (see
Figure 4.).
5. To determine the size of the deck for pickups, the width
must clear between the wheel wells, and the length must be
just short of the inside length of the bed with the tailgate
closed. For vans, the width must clear not only the wheel
wells, but also any shelving or cabinetry fastened to the
sides of the van and fit out the rear doors. The length must
be just short of the inside length of the load area with the
doors closed. In either case, the size of the deck may be
considerably wider than the width of the bed rails, depending
on the space available. We suggest using 3/4" plywood that
is 2" less than the inside length of the pickup bed. In full size
vans, the width should be 1" less than the inside dimension
of the rear doors when fully open.
6. Lay the decking material across two sawhorses. With the
help of another person, place the Deck Assembly upside
down on the deck material, 1" from the rear edge, and cen-
tered side to side. Using the Deck Assembly mounting angle
holes as a drilling template, drill 5/16" holes through the
deck material. Bolt the Deck Assembly to decking material
(see Figure 5.).
