Yes that is correct. That's the number I used to find my replacements. Sorry for the confusion, The complete part # I ordered is W21-760-7076. It has the NBD-10010 cap & the NBD-10795 piston with an extended height of 11.25". Matched up perfectly with my setup & looks to be exactly what the OP needs.
