Not without buying aftermarket axles. The A body 8 3/4” small bolt axles have a unique axle offset that is specific to the 1 3/4” wide brakes. The offset is different, the brakes from a B body are wider, have the large bolt pattern on the drums, the center register is larger in the B body so the hole is bigger in the center of the drums!
The rule here is pretty simple for A body 8 3/4”, you either run small bolt axles and the original 1 3/4”x10” brakes, or you get aftermarket axles which will be large bolt, and use any large bolt brake setup! You can use your 7 1/4” 10” brake stuff provided you have the proper backing plates, and vise versa.
