These Corvettes can’t tolerate a clutch that doesn’t release in less than about .560 inches. I would test the clutch in a press and if it doesn’t release in less than .560 inches it won’t work in a Vette no matter what release bearing and/or pivot ball you use. I have run into this in my car. You certainly don’t need 1/2 an inch of bearing clearance. As little as 1/8 of an inch will be fine. Here is a great thread to read by a very knowledgeable and well respected member here which also applies to our C3’s.
