Dink, if you don't end up getting what you need, consider making your own needles. I made my own from watching Amy's tutorial
(scroll to the bottom of the page).
The size you're needing is a fairly common dowel rod size. You can go to either a craft store, Wal-Mart, or a home hardward store to buy the dowel rods. Just take along a needle guage. Slip various size dowels into the holes of your needle gauge until you find the right size dowel you're needing. It took a little elbow grease, but it was super simple. I made a few pair that way, and the larger sizes seemed the easiest to make. My size 11 dpn's cost me less than a dollar to make, and an hour or so of my time.
