SRAM X9 9SPD + 9SPD Cassette w/ 10SPD Saint Der.

PLEASE use a very thin base washer to prevent marring when the nut is tightened. ALSO, you will need a slightly long M5? Bolt for the added height. Just experiment, takes only a few minutes. Pliers may be needed to prevent line twisting when tightening. 1/4" Nut height or your local equivalent, Zinc plated is good. Sorry for low quality, but you get the point.
