If it is the stock equipment, then it has a "self-adjusting" clutch quadrant. To adjust it, you pull up on the clutch pedal with your hand as high as it will go and you hear it click. Then, with your foot, press the pedal all the way to the floor.... you'll hear it click again. It is supposed to be adjusted at that point. No need to remove the steering wheel, or remove anything for that matter. Even when removing/replacing the quadrant, cable, or the clutch it'self, there's no need to remove the steering wheel.
With the adjustable quadrants/firewall adjusters, to take up slack in the pedal, you just turn the firewall adjuster counter-clockwise to tighten up the slack or clockwise to loosten it up. I have the UPR adjustable quadrant and firewall adjuster and recently I got a new clutch cable....which I knew would stretch out a little at first, which it did. I had a little floppiness at the top of the pedal's travel. I just adjusted the firewall adjuster (counter-clockwise) and tightened it up and now it works great. The adjustable pieces are definately the way to go.
Hope this helps!
