Gaui main shaft question

[bk479]

Does anyone have any main shafts for these or any leads on who may have some in Stock I have looked around but come up with nothing

And does anyone know if the x4 or x5 shaft is the same as the 425 550

It appears that the NX4 and X4II take an 8x135mm shaft. The X5 takes an 8x172mm so it won't work. You can buy a set of two for $10.50 from one of these links:

Sorry but I'm not really sure on the 425 or 550.
