Over-axle floor pan patch pieces?

[Dohc Rocks]

I've seen the area patched in the photo below rusted out on many A bodies. Is this part of the over axle floor pan available as a stand alone patch panel?

Looks like AMD makes it but its expensive and currently out of stock.

Search around, maybe goodmark or sherman makes it but I wouldnt count on it.
