It only took me about 10 minutes to install them. They work great and fit fairly well, although I want the top link to be close to the pin and strut they connect to. They have a fairly loose fit at the top, while the OEM part has a captive plastic sleeve that keeps it nice and snug. However, I can't imagine this being a problem unless you open your rear window a hundred times a day. Hey, I'm just glad the glass didn't fall on my head while loading the car! happy customer
