1) Unbolt accl pedal, you need room to turn the clutch master cylinder rod.
2) Use 12mm wrench to loosen rod lock nut in picture identified by arrow.
3) Depress/Release clutch pedal with one hand while turning the master cylinder rod with the other hand, you have to relieve tension to turn the rod.
4) Tighten the lock nut
5) Install accl pedal
Key here is depressing the clutch back and forth to get the rod to turn, otherwise your fingers will just slide on the rod. I left only three threads left on the rod, the clutch pedal now sits about 8mm higher than the brake pedal, I like it much better as it grabs right away, I have eliminated the free play too and most importantly it seems to have fixed my issue with 2nd gear, now I can achieve fast throw high rpm up shifts into 2nd.
