Just a heads up that Trico still sells the metal blades that came on our cars. They are called the classic series, NAPA carries them as well. They are identical to original except have "made in australia" in very small letters on one side (put it down, can't see it).
Use a large flat blade screwdriver to lift up the arm....slide the square 1/4 shaft between the wiper and stub and you can easily lift it off. Remember to remove the guide arm clip first with a small screwdriver.
