This video details the instructions for changing the height of the pedal without modifying the rod or changing the position of either pegs or boards. This mod will work on any F3, will allow up to a 2 position change in either direction (From P3 to either P4 or P5 or back to P2 or P1). You also will be able to adjust the height in 1/2" increments so you can get the height you want.
