Since my cooktop range is 30+ years old, it's hard to find replacement parts at the local big box store. Appliance Parts Pro had the correct parts to do the job. It's worth noting that according to the website feature, these pans and rings did not fit my model. However, they were listed as fitting similar models and were designated for GE hinged-burner cooktops. I took the chance and ordered them--they fit just fine.
