Hello, I have had my Resolute III (Double Door, Top loading) for 40 years now. It is my main source of heat in my home. I'm starting to have an issue with the left door. I think I may have the issue fixed but I'm trying to get ahead of the potential future issues with aging. I am looking for replacement doors for the Resolute III - (double door). Does anyone on this forum know where I can find these doors.. I have been on the net but no luck so far. Thank you for your feedback!
