Thanks for the advice. I put some signs up around the neighborhood and went to my local recycling shops. Nothing.
I don't want to abandon this machine as I'm aware of only one other in existence (a Dr. Pepper version the Pennsylvania Gameroom Warehouse was selling as a project). Not to mention the time invested in cleaning and getting it work.
Re-creating the can rack is not impossible and I'm drawing up the plans now.
In the meantime, here's some pics of the outside.
