Need list of GM "A" Body cars

I have a 1965 El Camino with drum brakes. I am going to change the fronts over to disk. I found out that 1966-1972 GM "A" Body spindles are interchangeable. I can't find any list of A body GMs. Can anyone help? Thanks

Chevrolet Celebrity
Pontiac 6000
Oldsmobile Cutlass Ciera
Buick Century

:p

Thanks for the help. Searching the pick-a-part should be a lot easier.
