05 Hunter 36 leak above nav station

[Shearwater 36]

Any help on (partial) headliner panel removal. 2005 Hunter 36. Have water leak above nav station possible source grab rail on deck up above. Cant figure out how to access bolts on bottom side to rebed. Looks little easier to access through head ceiling but guessing wall may extend up to bottom of deck where I could not reach across. Some pictures to help would be great. Thank you in advance!

Check this thread, I did it to install a new clutch on the coach roof and a wind speed instrument above the companionway
