Looking for simple iPod dock prototyping adapter

Hopefully one of you can help me. A while ago, I saw this iPod dock adapter prototyping kit that I can't seem to find anymore. I've seen other ones that won't work for what I need, what I need is what is like the attached image. If someone know's where I can find the type in the picture, please let me know.

Thanks.
