I've taken these off various years late model GM A-Body,but I think GM X-Bodies like Buick Apollo,Olds Omega,Chevy Nova,& Pontiac Ventura used these too throughout the mid to late 1970's but can't confirm because casting numbers are not always the same as the part # application listed.
Hope this A-Body list helps some.
