Ok so I looked around for ferrule's and I actually have some, they don't work, they're too big to fit inside the derraileur housing clip/thing.
I guess I'll take a picture of this housing thing and post it when I get back to the states (tomorrow hopefully)
...wait, actually I think this is the housing thing, apparently it's called a pyramid 3-speed connector

I think, unless there is some really small and specially designed ferrule that i can't find, what I need is a cable designed for 3-speed hubs
ok, well this is a long post. I've email bike parts usa to see if they have the part.
Otherwise I've found a vintage bike club that seems to sell the full cables so I'm going to try and order one of those. Thanks for the help.
oh, BTW
