Vessel Sink 2" Drain Opening, Need Drain?

I have a Porcher Sink that was shipped to me from a company that went out of business and now I fine that it has the European Sized Opening.
My Sink is an Overflow Sink, and my Hardware is Toto Soiree tl960sd chrome, which ofcourse is American Sized. Where can i get a drain or flange to fit?????

Thanks, I have tryed everything, hours on the internet.

Maybe it wasn't such a good deal after all...

Try your local American Standard dealer,
Porcher is a division of Am. Std. perhaps their rep may have a solution for you...

I am in contact with them and they think they have a drain that will work.
Just hope they are right.
Sometimes everyone makes mistakes. Just have to correct it.

Thanks
