Ah I see okay thanks! I kinda assumed that they would provide a few options based on what I have read about diff years of the pyramid reed having diff size crank seals. I contacted dos and they made the party pack of everything available again so I went ahead and picked that up. Pretty good deal compared to pricing out individually. I’m pretty sure I have a nut on the sprocket but it’s up at the shop so I’ll have to check later tonight.
