Has anyone replaced the masthead pulleys on a H40? Bottoms are done now for the tops. My sail maker say's he has a mast off a mid 80's H40 in his yard and the top pulleys are captured under a plate that would be imposable to get off while hanging from a chair. Is it different on a 90 model vs. a mid 80's model? Can it be done with the mast up? The traveler is installed (reinstalled that is) and the new sails are ready. She will be a sailboat in the near future once again.
