76 dart wiper knob needs to come out.

Basically what it looks like is a cog/gear looking piece under the wiper switch that looks like the one that unscrews on the light knob after knobs been pulled off. It looks like someone attempted to unscrew it before but failed horribly and scraped it up pretty bad.

Is it a round knob? I don't know this car very well to know what it takes. Can you post some pictures so we can see what you see?

I looked for some switches and this popped up. I don't think it is like this style so post some pictures.
