Xtra Raptor clutch plate thickness

[Thefudginator]

Hi Folks, I am new to this forum. I bought an Xtra Raptor which had some clutch slip. So I bought a new clutch plate set (as I intend to keep the bike for some time), but noticed that in the parts manual, there are two different part numbers for the clutch plates (so it appears that there are two thicknesses). Now I don’t want to assume that my set is OK, as it has all identical plate thicknesses. Does anyone happen to know if this matters or not? If so, where can I get the two thicker plates and how much are they? Before anyone asks, the plates that came out were all the same thickness. Apologies if this appears to be a daft question.
