there isn't a pedal box as such--you strip the pedals out in situ ,take note of where washers and plastic springs fit. i find when re-fitting it makes it a bit easier if you make a guide to fit in clutch pedal that is slightly longer than width of pedal bushes,and a good fit in bushes/quadrant. is also easier if steering rack coupling is un done [dont turn steering when undone you may cause damage to air bag clockspring-if fitted] remove keys to prevent it.
