Ghibli SS Clutch slave limiter adjustment

My Ghibli SS (probably the same on all single disc clutch Ghibli's) has the normal adjust rod at the slave cylinder to set clutch free play. However, there is also a second threaded rod below the normal pushrod from the slave. It is there to limit the total slave cylinder travel so the pressure plate cannot be "overstroked". Does anyone (Ivan?) have the factory specs for the setting distance of this rod. It is designed to hit the bellhousing to limit the length of the slave stroke.

 

Mike: Yes, that is the rod in question. My current thoughts are it should be set whenever a new clutch is installed, by observing how far the pressure plate can be pushed before overstroking. As the clutch wears, the TO Bearing contact surface moves to the rear, and with slave cylinder pushrod adjustments to restore "free pedal", the clutch cannot be overstroked again, therefore making the "second" rod no longer a factor.
