THE PLYWOOD PIECE MUST BE CUT DOWN TO 10" WIDE. MAKE SURE YOU CUT THE EDGE OPPOSITE THE NOTCHES.
Fig 12: The front piece of plywood is approximately 11.75" wide. The edge OPPOSITE the notches will need to be cut off.
Fig 13: Before cutting it down, use the utility knife and trim any excess glue off the edge opposite the notches.
Use a table saw (in photo) or a skill saw and straight edge, to cut the plywood piece down to 10" wide. Cut needs to be straight.

Fig 30: Silicon sealant should be applied to the following locations:
Under each of the small brackets, on top of each of the kick ups where the plywood will be resting.
Also along the inside of the long bracket where the plywood will sit down on the bracket.
Place the plywood down on the cab floor, into the long angle bracket, and screw the brackets to the cab floor with the #8 x 1" screws.
Use #8 x 1" screws to attach the two small brackets to the floor.
Secure the plywood to the long bracket by using five or six 3/4" screws through the pre-drilled holes in the bracket and into the plywood.

Fig 31 & 32: Attach the flat white aluminum pieces at each end of the plywood piece as shown.
Use 3/4" screws to attach the aluminum piece to the back side of the plywood (2 screws on each side).
Screws can be installed from under the vehicle through the opening under the floor or using the right angle driver attachment.
The aluminum pieces should extend slightly past the end of the plywood angling slightly away from the plywood.
These pieces will keep any undercoating or spray foam from coming into the cab area.

Fig 33: Before installing the metal transition between the plywood and the front of the floor the two small pieces of rubber edging
which were removed in Step 4, need to be secured at each end of the transition plate as shown.
Use one #8 x 1" screw to hold the rubber piece in place. One rubber piece will be used at each end of the transition plate.
Fig 34: The transition plate spans the gap between the front plywood piece (with the notches) and the floor in the living area.

After taping each end of the transition plate, undercoat the backside of the plywood piece (Fig 31 & 32)
Undercoating should be applied from under the floor to coat the plywood and aluminum brackets.
Spray foam insulation should also be used to seal up any gaps where water could find its way in.

18

Remove the masking tape and begin re-assembling the plastic trim pieces and the end panels.
Refer to Steps 2 & 3 to re-assemble the end panels and plastic trim.
