I would try to locate a Motorcraft unit.....
Look at
www.rockauto.com
If they do not list a Motorcraft one.....try
www.parts.com
This will get you to a website from which you drill down to the manufacturer.....and then you will see a whole bunch of websites.....which are dealerships that have placed their parts departments on the web. You may be able to save a few bucks on a Motorcraft part there.
