As old as this freezer is it probably isn't worth trying to identify and see if a replacement door liner is available but you might consider removing what's left of the liner and insulation and replacing the assembly with something like a piece of that blue insulfoam and cut it to fit inside the lid... I've seen a number of liners in old chest freezer doors (lids) that were duct taped to keep from falling down every time you open it up... Cheers, kooler
