Hello Jim,
I replaced the standing rigging a few years ago. It's not a huge cost - one of the joys of a small boat! I didn't replace turnbuckles or toggles, though, which would increase the cost considerably. I inspected them carefully and all looked fine. I bought from Jimmy Green Marine, which had/has a handy website tool for specifying each shroud and stay (and gave the price for each).
I had a dilemma because my old rigging didn't match the dimensions given in the Parker manual (see my previous posts entitled 'Rig Dimensions'). I concluded that the manual was wrong (at least for my boat, which is #002) and I carefully measured the old rigging (laid on ground and pulled tight) to specify the new.
The forestay has to be cut to allow it to be drawn from the furling spar. I ordered the new one unterminated, slid it into the furler and fitted a Stalok terminal (which I then filled with mastic to keep water out).
I hope that helps.
Best wishes,
Anthony
