Sorry I can't help you on finding an alternate source for those bolts. I am offering an alternative: Dzus fasteners.

It looks like you want to stay stock but these would 1) provide functionality on removing your side panels (1/4-1/2 turn unlocks the bolt), 2) are a common race modification (which would fit the look on such a fine machine).
I'm not near my D12 right now to examine which type of dzus we need. Also, one or two of the lower fairing bolts are recessed which may require sourcing the proper Dzus.
Again just an option and you're Super III will look great whichever you decide.
