I only mention this because having to have over 3.5mm of spacers behind a 9 speed cassette seems odd.

The FH-6500 did not have a spacer on the rear of the freehub body.
It also has a slightly different mounting depth in the interface between the freehub body and the hub shell. Not many bodies would fit properly with the FH-6500 shell.
