WTB 70 CUDA rear seat bottom brace

[0791ADUC 1970]

I’m looking for the brace that is circled in red in the picture. It’s the rear seat bottom section of a 70 CUDA that has rusted through. Maybe someone has a seat frame thats pretty much toast but the brace is still good and would be willing to remove and sell it. I believe it would be considered a brace.
Thanks
