Clutch plate thickness?

Does anyone know where I can find the minimum thickness tolerances/spec for the LC4 clutch plates - both the fiber ones and the metal ones? I've looked in the manual but there is nothing there. Just want to measure the old plates that I've replaced to see if they are under the minimum recommended which would explain my slipping clutch.

I had the same problem when I stripped my clutch to check it, this is what I used for reference, its for the 950 Adventure
