M_Boats: broken forestay mast fitting

My forestay mast fitting broke and I found out when the mast was down or it could have been more serious. I jury rigged a fitting in order to enjoy some sailing this last weekend on Odell Lake, Oregon. But now I need to know how to permanently replace this fitting where the forestay attaches to the mast. I would appreciate any ideas on that one. All there is left is the oblong hole in the mast where the fitting used to be.
