I am in the process of buying a dozen or so pre-made wire rope cable assemblies made with stainless steel wire rope and have been coming across a few good resources to pass along.
The first link come from the UK. Of interest to me in the first link are turnbuckles that have a swivel in the end (look at page 17). One their site they also say that the breaking strength of the forks are determined by the clevis pin and the threads. Obvious, but I'm not sure that I have seen it stated so succinctly. In the second link they have a round eye with a plate and a threaded stud which looks like it would be a good rigging connection. They also have them with a nut if you need to bolt from the other direction.
The next link is a rigging book from the US Coast Guard:
The end certainly has stuff that isn't very useful, but some of the beginning sections are full of useful references.
