I am getting back into windsurfing after around 15 years off and still have my F2 Lightning which I believe to be a 1986 model. The foot straps on the board have all disintegrated with time and I would like to either replace them or modify the board to suit screw type straps. The original straps attach by locating into holes in the board with a rectangular block which is wedged down into the hole locking them in. If anyone has a set of foot straps to suit the old type F2 system I would be keen to purchase them, or, if has anyone successfully filled the holes and fitted screw type straps - I would like to know what was used to do it and how you went about it.
