Getting worried about clutch master cylinder...any leads?

I've been searching high and low for a replacement clutch master cylinder, or even just a rebuild kit. I'm all out of options at this point. Local parts places are all tapped out, including the big guys, amazon, and even the junkyards. I had one hit on ebay but it turned out to be backordered. Does anyone have any leads on these? What have you done in the past? If anyone is parting out or has an extra, please let me know. Are there any interchangeable models, maybe with hondas of the same year? Thanks a bunch!!
