Didja try Jim's - the next link over? He's got them listed as small as a 32t on the drop down options for his sprocket adapter. He used to have 'em listed but he changed his site recently, I mention him cause his work is really good - give him a call?
He makes the stuff - so I bet he's got what yer lookin' for
Still - it's odd you've such a powerful chinagirl, heck - can't complain though lol
