Firebird Question
 

Need a Pontiac question answered. My brother is restoring a 1969 Firebird Convertible and has come across two liquid filled reservoirs, one on each side, by the headlight buckets. About the size of coffee cans. No electrical or vacuum connections. Appear to be oil filled. What are these, and what is thier purpose? Any help would be great!! Thanks--- Mark

They are counter weights used on convertibles, most often called cocktail shakers. There are two sets of these, one in the front of the car and the other is in the rear. They are perfectly normal.

Keep them in the car..Helps keep it from sagging in the middle.

They are a vibration damper to cancel out unnecessary harmonics due to the converts body structure. GM tech a la 1967... https://www.yenko.net/ubbthreads/imag...ns/scholar.gif
