Free play is irrelevant.
What you really need to look at is pressure plate departure. I shoot for .060" with the pedal fully depressed. Free play ends up being what it ends up being. Now this does assume your entire clutch linkage setup is not all wore out and is in good condition. If it is not fix that first.
Free play can become relevant if there is none, not trying to be an a-- just clarifying
Agree on the clearance and linkage, bushings etc. condition.
Will also mention to make sure all of the components like the Z bar. clutch fork. pivot ball etc. are correct as I have had some real hacked up
cr-p roll through the doors in the last 25 years
