I did quite a bit of research online to find the matching knobs, and a rep from one company suggested I try AppliancePartsPros.com. After quite a bit of time, and after quite a lot of help from someone there, we found a fit, and the new knobs were made from stainless steel, not plastic. Well worth the price, not only for the parts but for the exceptional customer service! That poor man deserves a big Christmas bonus!
