Due to limitations with the Transmogrifier some items to make this set 'perfect' were not available, however after several hours of searching through many many belts and gloves I have found some that may not be 100% perfect, but still look pretty cool, and are all plate, so you could be tanking Deathwing in this Stormwind set.
