Try the forward head
If I understand what you are asking, you can get to the area behind the forward anchor locker by removing the panel (4 screws) or the wall above the toilet, You are then in the aft anchor rode locker. There is already such a pad-eye there for the anchor rode, but I dont know if that is where they mean to attach the parachute. Do they mean to install another one on the deck? If so, you can get to the area the same way to install the backing plate and nuts, but you will find it takes a bit of bending and flexing to get your arm up there and see what you are doing, though it's possible.
