Source for replacement fastback cuda rear window?

That's helpful to have some options - thanks! I will probably look locally first (N.E. Kansas) just because shipping would be a hassle. I'm guessing polishing the glass is not an option? Evidently the small spots are from grinding or welding in the car when the glass was not protected.
Come on down to S. Texas........we got Corona coming out of our asses!!!!!!!!!!:rofl::mad:
Polishing won't get out the pitting or deep scratches.
