SDX Main Opener Mount with over-sized holes

OEM main opener pivots fill with dirt and rust, get stiff and eventually seize completely. As the main opener pin seizes inside of the main opener arm, it tears the flag tab off of the pin and the pin begins rotating within the mount rather than the arm pivoting on the pin.  This causes the holes in the mount to elongate and deform, and if left long enough, will destroy the mount.
