Where in the Warcraft 3 MPQs are the Skybox Models?

I need to find out where in the Warcraft 3 MPQ the skybox models (Blizzard Sky, Felwood Sky, Dalaran Sky, Generic Sky, ect.) are. Even just one of them would be helpful. I am making my own skybox and I have the texture I need but I require a model file to use as a base.

Thanks
