1979 special left side petcock

[yesiamspecial]

I'm looking for a 1979 XS1100 SF (special) left side petcock. My local Yamaha dealer informed me that these are discontinued parts so it's junk yards or search the internet. I tried a rebuild kit but the thing is pretty bad off. I need a new one (NOS) or a used one that doesn't leak. Again, I'm looking for the left side petcock.
