Well, the old girl (1973) is cleaned up a bit and the trailer is totally done. She is going to get everything but the hulls (which had serious delam) from a much newer Turbo 14. The one thing that is missing are the 2 shackles that go through the tramp for the jib blocks. Can't seem to find the size specs on the shackle that goes to the wire under the tramp. Is this a normal D ring type shackle or a longer type? Thanks...
