Where can I find replaceable pedal pins?

One Muni ride on my new Kona Jacksh*t pedals, and I already lost a pin. Not
sure if I stripped the thread or it just fell out. Anybody know where I can
buy these online? I searched for a while but found nothing. None of the bike
shops in NYC seem to have them. These are the pins that need an Allen wrench
and they screw in from the outside.

The Kona pedals are great by the way. Big improvement over the Odyssey
Twisted Pro.
