I have found that a bottom of a coffee cup from McDonald's fits perfectly into the front of the hole for winter operation. Your McDonald's cup may be bigger, or smaller. The one I use is a form type cup, perfect fit. and keps out the cold ...and inexpensive to replace., and needes no sealant..just fits perfectly snug into the hole.
