Sink Twice modified to function with Glacier Bay Dual Flush (top button)

This is a Sink Twice with custom modifications allowing it to function with a Glacier Bay model dual flush toilet.  *Please note - this is not a "perfect fit" for Glacier Bay's dual flush, but it is functional and is a good fit for the application.  It is also the only sink in the world that we are aware of that will work for this application.
