Ordered the correct replacement part from your website. Removed 2 screws on old support and 2 screws on track and installed the new part. Superfast part delivery, thanks, great price, saved my customer a bunch. Unfortunately the part was loose in the box. the box was crushed in shipping and one of three screw mounting spacers on the backside broke off. I epoxied it back in place. When installing the part I discovered that the factory used only TWO screws so it wouldn't have mattered anyway, SCORE! No harm no foul. NOTE TO SHIPPING DEPT: Maybe packing material when box is bigger than the part.
