Where are you located, I actually have two things that might help you.

I have a few extra of the connections that I would basically give to you for the cost of shipping, also I have an old aluminium extension that I managed to break, I had to buy a new one because it is now to short to allow me to go all over the boat. But for you it would work.

It still works fine and the broken end is covered by duct tape right now but you could add some kind of grip.

If you are interested in any of this just send me a PM on here.
