-remove split pins from the dowel pins on clutch/brake pedals
-remove the dowel pins from clutch/brake pedals which secure the plungers for the Master cylinders to the pedals
-accelerator pedal, remove the throttle cable from the throttle body/inlet manifold so you have ultimate slack. plastic clip that holds the cable to the accelerator pedal, unclip this
never been further than that myself, imagine there is now nuts/bolts that the pedals pivot on in the footwell, undo these taking note of where any washers may go, reassemble with the new pedals and be sure to adjust the throttle cable correctly/refit the split pins to the dowels
