Trying to identify material in rear trunk

[Monster Poodle]

Thanks for info BirdDog!

I did get lucky on the wires. I'm replacing the friction tape on the wiring this week to get get rid of the mouse funk you can see. Will look over closely for cuts.

The material needing replacing is glued on, so I don't think it can be salvaged. I'm leaning towards using
Thermo-Tec One Sided Thermo Guard Flame Retardant material, since it will provide head protection and has a carpet like material for noise and vibration.

I had to throw away liners and such, so Wally will be a good connection for that I think.
