Spirit level for Ukranian front sight

[bear tooth billy]

I lost the plate and spirit level that fits into the Ukranian sight.
They were made by Red river sights, which I believe is out of business.
Anybody have one of these laying around. I contacted MVA as they have
one that looks like it, but I would have to take mine off and send it
to them to see if they can fit one.  Thanks
