There is no need to take the staples out of the flaps. Just pull out the old rubber around the edge. Cut a new rubber flap that consists of two concentric ellipses--never mind the center details in the old ones. Shove the rubber in the flapper and done.

You could use a cad program to draw a 45 degree ellipse with a 5" minor axis for a really nice fit
