Where can I get a pull cable for drivers side footvent?

He's talking about the vent under the dash on the driver's side (footvent). I dont know where to find one either, mine was missing when I bought the car, so I'd be interested if anyone knows where to get one also.
 
Sounds like something that would be relatively easy to fabricate.

Trip to the local hardware store for some cable and ends. Since you can't see it anyway, it's not like it has to have the original look or anything.
