2006 3600 Sovran

[Final Pursuit]

Just brought this boat home 5 days ago. So much to learn. I wanted to pull the fiberglass helm panel forward. I saw the hinges at the bottom. At the top on each side there is a recessed area with 3/8’ nylock nuts.i thought those were supposed to be removed, however they just spin along with the bolt or stud. Thinking I’m not doing this correctly. Is there another method? What am I doing wrong? All help appreciated.
