We wanted to keep pushing our project ahead, and as we did, we found times when it was appropriate to shift gears.

As we began to run interior wiring for speakers, power windows and the third brake light, we realized it would be appropriate to protect the interior surfaces first.

We chose to buy some truck bedliner from WalMart to protect the inside of our vehicle.  We put on two roll-on coats.  If you do this work yourself, you must do it outside.  The fumes are overpowering.

After rolling on the bedliner, we ran our wires and taped them to the fresh clean surface.  Once the wires were taped in place we cut our interior insulation to protect the bedliner finish.

In thse photos, you can see the rear seating areas of our truck, as well as the use of this 3/8" fiber insulation with double reflective aluminum layers on top.

We purchased our insulation from LMC Truck, a producer of OEM-quality after-market parts for classic Chevy and Ford trucks.  You can also buy this insulation from Summit Racing of JC Whitney.

We used spray-on adhesive for vertical surfaces, and then used aluminum foil tape to make-up all the seams in the insulation.

Note Right Rear Passenger Door Handle and Power Window Switch in the upper left corner of the photo. 

Eventually the door and handle area will be covered with thinner insulation and covered with black vinyl upholstery material to match the black Euro-sport seats with four-point harnesses.

Note the Third Brake Light Wire that is taped to the bedliner. 

We placed this wire in a location that will avoid conflict with our seat brackets, which will be bolted partially on the angled floor that ramps up to the center hump.
This photo shows below the rear window.  Note Third Brake Light Wire and Speaker Wires that emerge from under the insulation.

All insulation on the floor and window areas will be covered with black carpeting.  The carpeting will be attached with velcro or glue in key locations.

Also note that the entire back window area will be insulated and covered with fiberglass paneling in order to better sound and heat insulate the vehicle.
