Can anyone provide guidance on how to replace the gate stanchion on a 34 MkII. I removed the bathroom cabinet hoping to gain access to the back side of the stanchion, but there is fiberglass structure preventing access to what I would think would be nuts attached to the stanchion base mounting screws. Is it safe to cut the fiberglass structure there without damaging wires, etc? I could not find any guidance in past tech notes. Any help would be appreciated.
