IT FITS ALL SOLID AXLE EXPLORERS WITH OR WITHOUT DRUM BRAKES. PERIOD. THEY ARE ALL THE SAME.
Did you hear that?
You can't move your Ranger brakes to the Explorer axle (should you with to do that in the meantime) unless you have the explorer backing plate. Although the shoes and drums may be compatible, the backing plates are not.
Some 4x2 Rangers have 9" brakes also -- none of their stuff is compatible to swap over.
That should cover all possibiliities, lol, since your questions are VAGUE amigo!
