Is the EC pulley different in design, maybe the Code 3 pulley was the same and use the spring to do the driving?
Those buttons on your OEM pulley may appear to be attached to the clutch plate, but they are not. As you mentioned, they are spacers. The driving is being done by the spring bars. These plastic (or teflon?) buttons are loose and will actually fall out when I pull it apart. In that pic. they were just out of the hole a bit and cocked to the side, but they fall readily back into place. These are not the problem; it's the spring bars and the rivets as I see it.
