Since the fridge was an older model, it had screws behind the gaskets. First, I removed the freezer door, then I loosened the screws and removed the old gasket. I then placed the new gaskets, corner first, then worked my way around the door until all sides was done. I tightened the screws. For the lower door, I didn't remove the door but I removed all items from the door shelves. Loosened the screws, removed the old gasket, then placed the new gasket one corner and worked my way around the entire door. Some of the screws I needed to completely remove them so the gasket lip can fit into the groove. Then tighten the screws. Over all the project took about an hour to complete, not difficult at all but be patient while placing the gasket as not to tear them.
