Hi. I'm Smitty. I am a professional appliance repair consultant here to help you diagnose, and repair, your appliance.
Gordon. We are not the manufacturer. We are a pay for answers web site. Unfortunately some of the advertising done on our behalf is somewhat deceptive.
If Sears can not get the part then your best bet is to keep an eye on places like E-bay, Craigslist, and your local newspaper want ads for someone selling one of these for parts.
Sorry for the bad news, but once a part goes NLA (no longer available) there really isn't any other option. This is especially true with Sears as they do not make anything they sell.
