I purchased a 350x with a new clutch.Wasn't long and the clutch was slipping.Tore it appart to find new fiber plates.Had used metal plates.You easily tell they weren't as new..Measured both and they were good.Clutch was adjusted properly also.I purchased a whole new clutch kit.Didn't know what fibers had been installed.Everything worked fine.Strongly suggest the whole new kit.The clutch will work so much smoother also.For the little extra money,good insurance.Look what a gasket will cost,times two.You hunt around some and clutch kits can be very reasonably priced.
