Still not sure what you are looking for calipers for, GM stopped the rear disc setup on the Cadillacs (RWD) in the 1979 model year. If you are finding calipers, you are getting them from a FWD car like an Eldo/Rivi/Toro, which by the way, ARE the same ones used on the 79-81 Firebirds with the disc brake option.

In comparisson, the 76-79 B/D body rear discs are 5x5 drilled rotors with a larger caliper (more like a front caliper size wise) and beefier backing plates. I wouldn't use the 79-85 stuff, but it is for sure easier to find.
