I recently purchased and installed the glass turn signal lenses for my speedster; thus having no need for the opaque plastic turn signal lenses that came with the car.
I don't know if anyone has a need for the "stock" V.S. lenses, but I'd be more than happy to give them to you. If you're local to the Bay Area, I could hand them off to you in person.
If not, I could send them.
Just thought I'd go this route before throwing them away.
