it's very easy

there are 3 nuts that hold it in place plus a bolt hidden away up top somewhere

just use a long extension and make sure you have a torch

just be aware that the pedal box also holds the abs stuff on the other side of the bulkhead, so you only need to to the top right and both bottom nuts, the top left one "should" be just sitting there doing nothing but holding the abs in place

also it's easier to remove the clutch cable by pressing the pedal and then jamming a screw driver into the fork so that it's just as easy to put back in again afterwards

mine collapsed years ago and i spent money on a new clutch before i figured out it was the box
