Thanks for the response.
The rig has only 4 forks----They are used on the short "Y" from the back stay to the aft chain plates.

I have a single back stay--that runs to a diamond plate. At this point splits into two short legs(approx. 6 ft .) which run to a chain plate port and starboard. There is a fork at each end of these 6 ft legs.

The forks attach each of these legs to the chain plate and to the diamond plate.

I would gladly incorporate a 7/16 toggle into the set up but I still have the same problem of attaching the fork to the toggle.

The Hayn Catalogue gives "most" of the measurements of the fittings but unfortunately not the measurements I need to tell me if there is enough meat to bore.

Why do they do this sort of thing--it complicates something very simple.

Funny though---I have a few "old tomes" on my bookshelf that state "the fork is WEAKER than the eye." I prefer to agree with you.

Thanks again for your help.
