Hi again,
Pitting is a relative term, and a little would not be a major worry. But what looks like a little to you might actually be a lot. Go to this page:
http://marinesurvey.com/yacht/corrosion_1.htm, and scroll to the bottom to see intraganular corrosion radiating out from small surface pits. From your photo, I'd have to say that your chainplate is more like this than you would like. You have classic, hidden-in-the-deck crevice corrosion.
At least you know how to get them out. For that matter, you actually cared enough about the rig to take them out. We just need to calibrate your eyes.
As for the rod noodles, I've bent them in place with no problems, but it is a finicky process. Get precise measurements, and you can get the bends done for you.
Fair leads,
Brion Toss
