Technical Help needed 46 Ford floor pan

On my car is the floor pan real bad so I'm looking for a good source to get a patch panel
The front piece which is kinda 45 degree I already got now I need the piece which buttons up to that and reaches under the front seat

1946 ford sedan delivery

 

to my knowledge no one makes accurate repro panels for these cars.. rather they ONLY make "street rod style" flat panels that can be welded in..

on my current convertible project I found another donor car to cut the floor out of .
If I did it again, Id get new rockers.. and build a flat floor..

 

On my 46 sedan delivery i got everything fro direct sheetmetal
