Where to get daedric cuirass on oblivion for xbox 360

Sometimes you can find a Daedric Curiass on some of the daedra in Oblivion. There are a few places in the game that are guarded by daedra. To get the Arrowhead of Extraction on one of the thieves guild quests, you have to go to a wizard's lair, and there are plenty of daedra there. You don't find them very often, but daedra corpses are the best place to look.
