"Japanese making inroads in truck market"

Q: hello all i purchased a 79 trailduster recently. overall the condition of the body is good except for some rust underneath. the rusted panels are under the driver and passenger side floor where the bottom of the truck meets the side. they are the length of the door and about 8 inches in width. i initially thought that they are part of the floorpan but i am able to see through these panels rust holes. the floorboard appears to be directly above the rusted out part. does anyone know the name of the panels that im referring to if so where might i find replacement panels thanks in advance guy .
