Spare parts for B-Max4 Champions Pack Shocks

[yokomobmax4]

Hi, I am looking for three parts from the B-Max4 champions pack shocks:
1. O Ring (10 mm)
2. C clip
3. Collar White (the small one)

Problem is that the assembly instructions don't show part numbers so I won't know where/how to order. Any tips where I can get these parts or where I can find the part numbers?
(And yes, it's not the orig. plastic shocks and also not the big bore x shocks, it's the champions pack shox).

Cheers, Oli
