I only live about a 5 minute walk from the water but need to borrow my wife's car to transport anywhere as I ride a motorbike. I want to build a trolly for my Formula board and was wondering if anyone has a broken fin that I can chop the head of to locate the board through the finbox. It's a Starboard F-186 and I think it's a deep Tuttle? I'm on Sydney's northern beaches if any one can help....
