Here is a video of what I did. As you will see nothing special…remove an endcap, remove one nut, swap pedal bodies, replace nut (torque), replace endcap, go have fun.
This video was the right pedal body so the nut was left hand thread (left to tighten, right to loosen). The left pedal will be normal right hand thread. Both endcaps are right hand thread.
Endcap is 6mm hex.
Used a 9mm socket on nut. Torque on the nut is 8-10Nm according to GPLama but I have not confirmed this…I trust him
