Traveller rear floor panel repair

[Higgorama]

Hi,
I’m trying to identify the correct replacement panels for a 1961 Traveller for the floor behind the gas tank (specifically the 2 rear floor corners). I’ve searched several parts websites and don’t see anything that looks like the correct shape. What is that section called? Those rear corner floor sections are flat - maybe easier to just cut & weld patches?

Thanks
Mike
