For those modding their clutch lever and having an issue accessing the 10 mm nut.
Many of you have or will watch Tremonte's video on the short lever install may have an issue accessing the 10 mm nut located on the clutch side. The issue is that a plastic piece eliminates any possible space for your socket to access it. Quick workaround to it is to remove the plastic piece. Remove the black screws circled and the plastic piece should drop on its own but should hang.
Reinstalling it is simple, the only catch is that you have to hold in the white piece (circled).
