You will have to basically bottom out the slave cylinder in order to get the 3/4 inch movement needed at the clutch fork. However, bottoming out the slave cylinder will also put the throwout bearing in constant contact with the clutch. On mine I backed off the slave cylinder rod while working the clutch fork by hand and looking into the bellhousing opening with a flashlight. When I could see slight movement of the throwout bearing before movement of the clutch fingers I figured it was about right. I don't have a precise measurement but I would guess it more in the range of 1/16 inch free play in the slave cylinder/rod. 1/4 inch free play sounds like too much to get full stroke of the clutch fork. Seems I remember the slave cylinder has about 1 to 1.1 inches total throw - but a small amount of that gets lost in the linkage and free play.
