I can't find a replacement gasket for this 1960's model oven. Old gasket is woven fibrous material with metal mesh spring inside. Woven fiber extends from mesh and is clamped in place by window panel on door. Window panel fasteners don't show, so I'm uncertain how to unclamp the gasket. GE part number WB4K1 may be suitable replacement, but not sure. Any suggestions?
