Autozone wants $32.00 for one! Great price here on Amazon. more affordable. Installation was quick and easy. I found a good video on YouTube on how to install them. It raises and holds the rear window as it should. A problem. When I leave, I close the window. Damn, I have to use all my strength to close the window. I am physically active, training hard 3-5 times a week and have had difficulties. So I asked my 18 year old son to try it. He also agreed. So not sure if this is a malfunction or if I need to lubricate something or use it a lot to wear it down a bit.
