All, where the brake and clutch go through the floorboard is there supposed to be some kind of rubber piece so that the pedal rod does not rub on the floorboard making that horrible screech?

Worn bushings at the pedal pivot shaft will also cause the pedals to drag the floor pan. Jerry

On my 50 250 series GMC there are provisions on the interior floorboard to replace or install the felt inserts. My pedals are not one piece from the brake system but adjustable on angle looking in the engine compartment. I don’t know if the Chev 3100 has this feature.
The felt grommets can be replaced on a Chevy. My '51 suffered from cab mount problems and the pedals wore into the sheet metal at the top of the openings.
The pedals connections to the pivots might be able to be adjusted a bit, but the connections use mating grooves between the parts to keep them in the correct position. See the pic from the Factory Assembly Manual.
I would say that the issue with Jack's pedals are either the cab mounts have sagged a bit (if they're rubbing on the top of the opening, that's a big clue - see the attached pic) or as Jerry said, the pedal bushings are worn (that would likely make them rub on the sides of the openings.)

There's a grease fitting on the pedal fulcrum shaft. It's hard to see and it often doesn't get greased so the bushing wears, rubbing the sides of the floorboard hole. I bought bushings and had them fitted for grease clearance. The problem went away never to return. I grease that fitting every lube job.

Now there's something I didn't know. I guess I'll try to find that fitting tomorrow and grease it.
