A couple of points..
1. Pedal free-play
The crucial spec is that the throwout bearing must be pulled back about 0.125" from the pressure plate. A common mistake is to adjust freeplay up top @ the pedal, the problem with this doesn't take in consideration of any worn linkage parts.
2. Z-bar
It is easy to confuse between Z-bars as more than 1 may be the same width but have different tab positions for the adjusting rod. The crucial point is to use a Z-bar so that its tab position permits the adjusting rod to push the fork in a linear motion, so that the adjusting rod should be parallel to the bell housing.
