Does anyone know of a company in the Detroit, Michigan area that will service Chrysler & Koppin ice boxes. Ours are probably from the 1920's and while have been restored cosmetically and converted to operate using freon, the door seals are fraying and in need of being replaced. There are 6 doors, and maybe there is a better or more efficient material that can be used for the door seals. I've contacted appliance repair companies that service higher end new appliances, but they don't know of anyone who will work on them either. Any feedback would be appreciated.
