Komura 2x repair questions

I got a komura 2x for my 500 c/m and it won't work. I opened it up and there's not much to it. Just the lens grouping, a rod to turn the shutter thingy and a spring. I think the problem with it is the spring, because it's hooked to the rod on one end and goes down around the rod, but the other end isn't hooked to anything. It just scrapes against the metal housing that holds the lenses together.

So now my question... Has anyone opened one of these up and seen where the other end of the spring is supposed to hook onto? Better yet, does anyone have an exploded diagram or photo of the internals of the 2x extender?!?
