Here are links to two photos, one of each side of the manifold. I labeled them actuators. I also labeled the oil separator, but worst case scenario is that there's one on your car you can use. These are the pics the parts place sent me, I just added the boxes and text.
Once you find one, you should order the gasket set, but that's like $20 from Tischer. Also, assuming everything's attached, you won't need bolts.
