I think the Mavic Microspline is ID360 only (It's all they list), and older crossmax used derivatives of the FTX/FTS or whatever it's called.
Probably worth a double check on model year and hub type. Though SX is quite an old one isn't it?
Might be better trying to get a XD driver and using that, i think i've seen them in the older format. Or *an* older format...........
