No worries, the association has them. I purchased 2 but I don't believe I will outlive the first one. Mine was completely missing and when we would hit rough chop, water would come up through it and get in the cockpit. When installing it use superlube or any NON PETROLEUM based lubricant to get it in place so the o- rings don't roll on you. And do what Ebb recommended with Reenforcing the tube base at the deck its a great and necessary idea.
