My port rudder arm got snapped at a regatta over the weekend. It's the older, bent kind. Does anyone have one (or a set) to sell? I'll consider adjustable upper castings as well, but want to know if swapping the uppers out involves redrilling the blades. Also, does anyone know if replacing the arm involves redrilling the holes for the rivets? I'm guessing the holes on my upper casting aren't going to line up with the holes in the new rudder arm. Life is just never that easy! Thanks
