No parts showing up in VAB/SPH

[mmmmminty]

So basically I installed the the rework and the core mod... I open it up in the SPH and I only have...

I wan't to build a space station like the one in the video (https://www.youtube.com/watch?v=yxh9En_Rd6E) but I don't have all the parts.... How do I get these parts? Like the robot arms and such..... I've looked everywhere for a download... But only legacy and rework....

If you know the parts please leave a download link or something. I've heard that there are other mods that go with this mod to form creations like this... If so, what are they?
