How do you copy a fsm from 1 project to another>

[wheretheidivides]

I have a project, modified it, cleaned it up and now it can't find some stuff.  The only thing I need it to open the old project and then move 1 playmaker FSM over.  is there a easy way to do it?  I tried exporting but it wants to include tons of stuff.

Stick it in a prefab and drag the file into the other project.
