I'm converting to and old style mast(no comp tip) from a new comp tip version. My newer mast had a sail guide for raising the sail. The old style mast has a opening that is narrower then the new style and the sail guide wont fit in the track. I was thinking of grinding the edges down which will widen the opening allowing the guide to be mounted. Does anyone know of any problems with that idea. If not it the last piece I have to switch over. Thanks Craig
