Pontiac recommended different dif fluids for posi difs so I would expect the same from GM on your Vette dif. Look around standard part stores and I think you will find what you are looking for. I had a similar problem with my Trans Am and the right fluid was the answer.

What you're looking for is called friction modifier. Commonly used in limited slip rear ends to eliminate that clicking sound you describe. Usually comes in a 4 ounce bottle. Add the whole thing.
