What is your actual clearances when installed in the case the correct way..........you cant compare it to the old stack........soak the clutches as you should then try to measure the clearance in the case. There are some different steels and reaction plates that can be purchased to set clearances.......but we need to establish it first. It can't be hard to get a feeler gauge in.......you can use thin washers stacked to get an idea..........you can place then in 3 or 4 places evenly around then clutch pack and keep adding till you can get the snap ring in place. I aim for .050 here, but .040-.060 clearance shouldn't hurt anything with good line pressure........I wouldn't want much under .040. These are bigger diameter that the others so the .010 rule needs to have a little more on this clutch.
