Drilling my Zbar??

After looking into it a bit more the clutch pedal is literally tach welded in place instead of a normal clip! Figures...
Anyway, that makes me wonder if I deal with undoing that and lengthening the clutch pedal to gain the extra throw as described in that article posted above....or drilling a new hole 1" lower in the Z bar arm where the clutch rod connects....
What else can get me the extra throw needed to depress my clutch better??

I guess I can grind off the welds...and jimmy rig something else to keep the pedal in....yeesh..
