The first thing you need to determine is if you have the 2 ball bearing or the 3 ball bearing blade grips. If you have 2 ball bearing the spacer is larger and you have 2 bearings in each blade grip for a total of 4 bearings. If you have 3 ball bearing you have a total of 6 ball bearings. I changed the stock order to help keep the collective from sticking, the stock order puts a flat washer with the same diameter as the bearing against it, the outer and inner ring of the bearing both contact this washer which can cause issues. I will list both my order and the stock order leaving the choice to you.
