Help finding or constructing a new convertible top switch for my 68 Dart

In November it seems like a great idea to deal with a number or small, niggling electrical problems by ripping all the wires and heater box out of my Dart. Now it's July and I really want to put it all back together so I can play.

The switch for the electric top is kind of doctored, and I would like to replace it. Can I anyone tell me where I can find a working three way toggle switch (up, down, and stop) that is either original, or made to be a replacement to the original, or created to work well without shorting.

This is not a show car - just a fun project car. Thanks for helping someone new to the forum.
