I got mine 14mm allen wrench from here http://www.wihatools.com/.

I ended up buying two. I cut one in to a few pieces so I could put a piece into a socket. I called everyone in town to find one, and nobody had one. So I had to oder online.

I think SnapOn sell a 14mm hex bit socket, but it is like $20. I bought 2 14mm allen wrenches from the link above for like $10.
