Lucky Day-
I have added 2 handles like those in the your cockpit. I bought them from the C-Cory factory, complete with the correct hardware to mount the on the outboard side of my windshields, forward. These have proven to be a nice safety aide, and I also use them for fender tie downs which I can reach from inside the cabin.
I also added 2 like handles to the inside of the head on each side of the door to help this ol' man get off the pot.
The pixs are on my Sea Angel gallery. Hope this helps. By the way, the factory price was much cheaper than any other source and the installation much cleaner. Just check out how your handles are mounted from inside of your cabin and head.
