Right. Carpet that can be used to cover custom kick panels and match the interior.
Ohhh, custom, that's why. I'm with you now.
If there's nothing new that is known yet (which I doubt, but bear with me), another option is a parts car with a junky carpet, or even just an old carpet from a guy that replaced his.
I gotta replace mine soon, I just noticed there's a frickin' huge red stain coming from the battery compartment. Leaked battery acid or spilled bleach or something, I have no problem holding onto it and cutting it up if/when someone wants a piece for a project like that.
I found a match at Lowes ca 2006 for the texture but not the color. Some kind of boating or outdoor carpet. I spent some time with different spray dyes until I found a decent match. They look a little off under flash photography but with natural light* they look better.
By now someone must have come up with a better match for original.
