Lens replacement for ZY-T08/HD2010

After an accident, I need a new glass lens for my ZY-T08, which suits in HD2010 too. The diameter is around 57,5 mm.
I asked one from fasttech.com and they answered that it is not available at the moment. Also searched in familiar places but could find anything.

Any ideas?

Am I the only one with broken lens???

I converted a HD2010 to a monster aspheric, and may have a leftover flat lens for you.

When I get home, I'll check.
