Howdy,
Attached is the azure frame specs pdf. This should help. You can always pick up a metric bolt from the specialty bolt section of most hardware stores. They have a wide variety of types. I know this is a work-around, but hey it keeps you rolling.
I was unable to come up with the lower pivot pin for a MKIII, but I finally ground off a longer one and re-tapping out the threads to make it work. If that hadn't worked I had picked up a metric bolt and nylon nut to replace the pivot pin.
