I should have updated this earlier after receiving the E brake boot, but I didn't think about it until today after doing some horse trading with another member.
The proper alcantara part number for the E brake boot that matches the replacement shifter boot part number DR3Z-7277-AA is AR3Z-2404-B. Perfect match in material and stitching.
