I feel stupid when I read simple instructions in getting 2 #8 30 MM long and clean lub the 2 wholes on top of helmit and screw in slowly to release it. I did it screwed all the way in the circle did rotatate accidently 90 degrees as it loosened. It wont easily go back. Got 2 screws exactly 30 mm. Do I pry or what?
