Ordering was painless, and arrived promptly.
Installation matched the replaced units perfectly.
I used a flat screwdriver to remove the clips on the old strut, some solvent and a rag to clean the mounting balls, and put a dot of multi purpose grease on the balls to ease installation and prevent corrosion of the balls.
Less than 5 minutes work per strut.
Need to support the door when removing the old strut so that it doesn't close and pinch.
