I'll go one better and give you the mast track. Came out of my custom quattro that sh!t itself after 4months. Its in the garage somewhere. will have a look when I get back from Cairns. its pre glassed, just missings the block of d-cell that it should have been sunk into.
Hey Mark, there is an old F2 Maui Project board sitting around the side of my shed (fence side) at the beach shack, has mast track, fin box & 2 sets of FCS inserts. Feel free to swing on by and grab it - all yours champ.
