Hi, you don't use a wrench to lower the roll bar you use a straight rod. Click on the video below for the procedure. This is a difficult job if you are doing it for the first time. An 1/8" rod or even a 1/4" extension will work. You have to feel around for the spring loaded release lever. You will know it when you hit it. Hold the lever down then force the headrest down with your arm.
