Help identifying these black sponge blocks

[ballmon]

When I inheritied the 2002 Tbird, these black sponge sheet blocks (2.5" x 3' x .25") were in the glove box. (See attached picture below). After 8 years now, never understood what they are for and ready to throw out. Does anyone know if intended for Tbird? Thanks

No idea.

Have no fear. You can trash them if you wish.

A few years ago I purchased my bird from my dad. He could not longer drive. I've found a few things that I have yet to identify. I keep a little bag in the trunk for these types of finds.

There are similar tabs that are glued to the bottom of the hardtop shelf where it comes into contact with the top of the speaker grills

If anyone would know, you are the man when it comes to these cars. Thanks Bob.

Not sure if they were on all years. I removed them from a hardtop thinking that they were only there for shipping but after removing I wasn't so sure
