Bell covers for Stereomour II OPTs?

[oztayls]

I've seen some pics of Stereomour IIs with bell covers on the OPTs. I'm guessing the bell covers are not standard and that builders are adding these as aftermarket add ons? If so, does anyone know the correct size required so that I can pre-order some?

The current plate chokes come with metal covers.
