boot

This boot on the shifter is torn and I need a replacement. Its not listed as part of the shifter and i have no clue what its called to look it up. Can anyone tell me what it is and its part number.

I’m looking for a lower shift boot also called the cover floor pan for a 2003. The 97-02 is all I can find but they are way different than the newer models. Everywhere I look it’s not available, sold out, or discontinued. Daveysjeeps doesn’t have any either. Here is a pic just for reference...
