My bad-... I was thinking of the clutch fork arm. For the pedal arm I agree with KillerNight- Weld it up, grind and drill back to original. IF you don't have a welder there are plenty of welding shops that can do it all for you for fairly cheap.
I will send you a link to the hydrualic clutch set up. Basically I mounted the master cylinder for the clutch where the brake mastercylinder was, near the frame rail, since that space was open after I put in the brake booster and dual master. The clutch master cylinder lined up nicely with the stock clutch pedal after I modified the brake pedal to line up the brake booster rod.
