Most running rigging components are not specific to the boat builder. Moreover, most boat owners will choose to modernize and customize their rigs vs. replacing what the factory installed 30 years ago. There are lots of online sources for rigging components and every one that that I have tried has been excellent, except for D&R Marine. D&R has very limited choice, high prices, and are less helpful than other places. However, they are a good source for parts that are unique to particular O'Day models.
