Fastback Barracuda trunk info

There is a plywood security panel that folds and latches to divide the trunk space from the passenger compartment. In the color picture you can see it folded down when it's up and latched it meets the sides of the carpeted area at the back. Mine still has the security panel in it.
I don't have any pictures to show it in the latched position that are good
quality.
As for the trunk area I believe there was a cover over the spare tire and
a vinyl or rubber mat over that.
