Switching to a twin disk clutch will help your leg considerably. Stay with a street twin disk category which will hold twice the torque of your current clutch most likely and be a lot lighter to operate. You will have to go to an internal slave/throwout bearing. Most require a stop bolt on the clutch pedal (where internal slaves get most of their complaints. Folks skip that step & the slave hyperextends and starts leaking)

While you're in there change the aft crank seal: Fel-Pro BS 40645
and the forward input seal on the TKO: Timken 3638 Seal
