Downloading latest models

Hello Warmane! I just want to ask what to download on the new models released by warmane for Wrath of the Lich King Expansion. You see I already have the client with the original wotlk models downloaded on my pc and now i want to download the latest models because of the lit WoD tauren and troll model. The problem is my internet data is capped to 50Gb/ month only and I dont want to download the whole game client again just to get these models. I remembered only a couple of files are necessary to achieve this but i forgot. Thank you for all the help!
