Replacement shifter boot

Has anyone replaced their manual shifter boot yet? My stock one is all cracked and pealing and looks pretty rough. I'd like to replace it with REAL leather, unlike the original. Advance Auto has a decent all leather universal replacement boot, but the bottom of the boot is too small to fit around the square retaining ring. Does anyone know where I can get one that fits at a decent price??
Thanks

Dozens of them on ebay.
