I thought it might be good to start a thread where we can list sources for parts, including safeties, plumbing, and rebuilt thermostats. If we can stay on topic here and just keep it a list it will be a useful resource for future stove restorers:

Replacement Parts Incorporated, Everman (DFW area) TX. [url="http://www.erepco.com"]http://www.erepco.com[/url] Thermostats and TS11 safeties, Thermostats rebuilt.

Washer Specialties Co., Wichita KS
[url="http://www.wsconet.com/"]http://www.wsconet.com/[/url] These guys had the Robertshaw 9B pilot for less than Patriot Supply. Didn't check their other prices but they have a huge warehouse and are very knowledgeable about the old oven control systems and gas plumbing.
