Hi mate,
Im currently using the X10 ones these are a direct fit all you need is the little nut to fit on the top to hold the rocker on obviously and not the button screw. Im sure there will be some new ones that arent hollow in production soon enough.
This is what you need:
ROCKER CRANK PIVOT SHAFT FRONT (X2)
£8.50
Model: S110A
And...
M3 NYLOC NUT (X10)
£2.55
Model: XH007
