How bad is this corrosion?

If you aren't sure what counts as a crack, go to any auto parts supply and buy some dye check, used for inspecting metal parts. Clean the part, apply the dye, wipe off, apply the "developer" and you should be able to see dye in any cracks. Hardest part of it is finding the dye--but any real machine shop or auto repair supply will have it.

This works. There are other ways to check also:

K that is pretty unanimous thanks!

I was hoping I could save some money by keeping the existing turnbuckles, but I have a feeling that the rigging may not have been replaced since 1981... If so, and if I inspect all the turnbuckles and they aren't cracked and still turn, are they good? Or is fatigue a problem with turnbuckles like it is with the wire and swages?

Yes, the bronze turnbuckles can be reused unless they have been damaged, are galled or frozen or you just want to spend money for nice shiny chrome. Bronze doesn't have the same problems that stainless steel does.

Yes, the economy could use the money, but you probably could too.
