What are these?

I have these two circled parts attached to my voltage regulator harness. They appear to be some kind of resisters. The wire connecting them are in pretty bad shape. My question, what are they? Do I need them? Can I purchase them at most part houses? Thank You.

The white (grey) resistor is connected to the orange (F) wire. It's actually frayed and rubbing against the paint. Probably contributing to my issue in a previous post. Should I should remove from the equation or replace?

I'd say remove them , gently & take a good picture so you could reinstall them if needed.
But back in the days we installed capacitors & resisters to try & take noise & static out of radios.. CB Radios .

The radio noise suppressors chokes (capacitors) are not for spark plug noise. They're for electrical noise created in the ignition coil and voltage regulators.
The regulator may not need them once they go to the solid-state style you have pictured (vs the old electro-mechanical points setup of the originals) but the ignition coil can always benefit from one.
I left all of mine in place.

The one mounted to the voltage regulator is stock. The one mounted to the fender in the Field wire is added by a PO and I had the exact same one on mine. Including two others for a total of three added to the stock ones by the PO.
The owner had been a Montana based hunting club and they had all sorts of radio equipment in it originally. Guessing that your PO, just like mine, was a radio person and wanted as much noise suppression as possible.

If they're causing trouble, or just in the way, you can probably remove them like the others have said. Just a good idea to leave them as long as possible, and certainly leave the stock ones just in case.
You may never use AM radio, but on the off chance you want to someday, you may find that your AM stations are un-listenable with the engine running.

Top one with the molded plug is factory. Cleans up the radio noise of the voltage regulator.

The other one, spliced into the orange wire, is NOT stock. Someone was trying to do something. Not sure what it was. Is that the "F" post on the regulator? I can only guess that it was a filter to try and smooth the input to the field to try and smooth the output of the alternator. Never seen anyone do that before. I would remove it.
