Bill;
Find below a reply I posted sometime ago in another thread that talked about the fire barrier and your car being concourse.
Arlie;
When looking into the trunk from the rear of the car the only thing you should see is the cardboard backing and not the jute material on the back of the seat frame.
Another thing to consider: If your car is concourse you will have to do the following in order to use the steel barrier. Install the cardboard backing first over the 4 tabs that casey explained earlier. Then in order to get the steel barrier to fit flush you must lightly tap the 4 tabs with a hammer and press them into the cardboard backing then install the steel barrier over that. This way when the judge looks into your trunk from the rear all they will see is the cardboard backing. Be careful not to press the tabs through the backside of the cardboard backing (use the hammer at the base of the tab with an upward motion). Since my cars are not concourse I didn't worry about this particular item. I just pressed the tabs all the way flush. Also, remember after installing the screws or bolts which ever you use (do not use long bolts or sheet metal screws) short is the key here, cover them with body color paint to match the inside of your trunk. I covered mine with black since that is the color of my trunk area. The judges may pick-up on the screws/bolts protruding through the back seat frame but, they will have to have a sharp eye. Not many of the concourse judges have run across the use of the steel barrier and by covering them with body color paint they may not even see it. they would have to really lean way inside of the trunk to see them. Since I judge street driven and daily driven class, this is one item we don't worry about. Last but, not least, make sure any barrier kit you purchase comes with a tube of clear silicone. This is used around the frame of the car to keep the barrier stable and not create any squeeks from the barrier flexing while the car is moving. Hope this helps.
