I noticed on my car that one can see the back of the rear seats from the trunk. Looks likle something is missing.
Is that this"1967-1969 Camaro Rear Seat To Trunk Divider Hardboard, Without Jute Backing" https://www.rickscamaros.com/1967-19...-179097-1.html
?
Does it just fit behind the rear seats? How do you install it? I was expecting something like this board but going inside the trunk, not behind the seat in the car.

 

There is a section of cardboard fits across the seat back and is suspended from the hooks the seat back hangs.
