Just file the plug down to the next size (i.e. 13 mm to 1/2"). That's what I did and it worked great. If you want to replace it with a new one, you'll most likely have to go through a Ford dealer as AutoZone and Advance Auto in my area didn't carry anything like the OEM one. In the future, change your own oil and make sure to use a box wrench and lightly tap the wrench with a hammer to break the seal. DON'T use a socket wrench = TOO MUCH torch and a sure way to round off the edges.
