If you're not dead set on a 2 tap jockey box, I have a 1 circuit cold plate that looks like this:
It is already in a complete jockey box consisting of a small coleman cooler and has the appropriate connectors and a shank for a faucet; it is missing the faucet since I'm currently using it on my kegerator. The other side just has a hole drilled in the cooler with no shank. It needs to be cleaned and probably needs new tubing but let me know if you're interested. I could try to get some pics.
