[TR] Measuring end float question

[Tony Drews]

Mark, I don't know the answer with certainty (regarding the Gunst 
throw-out), but I'd certainly put pressure on the crank towards the 
rear of the car to measure the "zero" position.  Then you can have 
someone push on the clutch for the other end of movement (or pry the 
front pulley forward gently).  Since everything is floating in oil it 
shouldn't take too much pressure to move the crank fore and aft.
