I need to replace one of my lifeline pelican hooks (ker-plunk) on my 1974 Catalina 22. I ordered a 1/4" but it was too small. Next size is 5/16" but I think that will be too small too. Next size after that is 1/2" but that sounds too big. I brought the lock nut to my hardware store but amazingly they couldn't find a bolt that would fit it. Any help on the matter would be greatly appreciated as usual.
