The NX5 uses an alternate linkage. Well, less linkage really.

From the parts book, it looks like it's just a male & female M6 rose joint, rather than two male (one LH one RH) and a threaded adjuster rod.

NX5 road shift part numbers are:
24711 NX5 004 - Rod end 6mm, A (Male)
43506 NC8 000 - Rod end 6mm (Female)

I would imagine that the position of the gear pedal and selector shaft is the same or similar on both NX5 & NXA, so it should be possible to buy a couple of M6 rose joints. Getting the correct length would be the hard part.
