Cocktail shakers were used on 67-69 Camaro, Firebird and Corvair convertibles. There are 4 part number due to the brackets for each corner being different. Otherwise they are the same. This was determined through searching factory manuals from a closed dealership parts dept. All 4 were missing from my 67 when I bought it. I had no trouble locating some on E-bay at prices from $125 to $250 EACH! Then a listing came up showing them fitting "early GM". I got the whole set for $80 plus shipping. Good luck!!!
