I recently installed a 50" OZ LED Light bar and some Wurton Mounting Brackets to my 2014 JKUR. So far the Bar has withstood a near constant 3 week torrential downpour with no signs of condensation build up, and I am greatly pleased with it to date. However, I cannot figure out how to keep the bar from spinning relatively freely on the screws that mount it to the brackets. Essentially it is just rotating on an axle. I have added washers / lock washers / and rubber spacers and still have had no luck. With the new mounting hardware added (including hexlock screws) It still rotates relatively easily. Anyone have this issue or have any suggestions?
