This may seem like a dumb question, but what exactly are "Cocktail Shakers"? I worked as a mechanic in the late 70s and early 80s, and have never heard this term before.
The cocktail shakers are the oil filled vibration dampeners located in the four corners of convertable Firebirds and Camaros. The rear two are 50 lbs. each while the front two are 25 lbs each.
