Not sure why this is saying Dragon Soul... Once in the temple, after the first boss, if you walk to the left of the staircase that leads down into Ahn'Qiraj, there's a room with NPCs. They give you the quests for the helm, greaves, legguards, and spaulders.

This quest is repeatable should you have the mats for multiple quest turn ins from farming AQ40. It is unconfirmed if each turn in will still yield reputation past the first completion. However should you be able to this is a very easy way of farming additional rep.
"You must also attain Friendly reputation with the Brood of Nozdormu to complete this quest." Wonder if this quests are still possible to turn in since the whole 'recreation' of AQ since Cata..

Description
The Twin Emperors... their incessant whispers are slowly taking a toll on my sanity. They mock me, knowing I cannot step further into their domain to save my brother Arygos. In my visions I see their monstrous faces adorned by powerful crowns. But I will have my revenge... I will transmute these symbols of Qiraji power to ones better suited to our needs. Bring me the components I require, {name}. I will give you a headpiece of unmatched power.
