That part was only used on that model dryer (ie. very rare!). I wouldn't hold your breath trying to find that part. There do look to be a couple used ones currently available at the following link.
They're asking a ridiculous price if you ask me. If it is an option, maybe you can make them a lower offer?
Alternately, you might look for a whole dryer of the same model to rob for parts. As I said however, that part was only used on dryer model MCE8000A so will pretty rare too!
