Ralph, is it possible there is part of the door flange we're not seeing, due to the angle of the photo, and that is where the gaskets are mounted? I'm not that familiar with these refrigerators to know for sure how they are built. We're not really seeing the entire inner side of the door.
What I think is fascinating about these photos is that it is obvious that the cabinets were updated at some point, maybe in the 1980s or 1990s? Yet, they went to the trouble of keeping and reusing the old appliances. Somebody sure loved their original GE appliances.
I can't remember another time I saw a Craigslist listing like this with newer cabinets and older appliances.
