Own 2005 hunter 30. Stanchion broke off port side near waste clean out. Only nub left. Can't get to bolts on underside of plate because of shelf in locker and can not reach bolts. Any suggestions on how to make repair?

My understanding is no nuts on the bolts.

I have a 2002 Hunter and she has aluminum plates threaded to accept the bolts.
