for the DIYers, you can use a few cans of non destructive dye penetration like Magnetrol (sp?). It will 100% let you know if you have crevice corrosion, cracks, etc. You have to know how to use it, but not rocket science.
Other than that, have PSC replace them with new. Not so great a cost when you consider the cost of failure of the current rig. What is worse, $800 in new chain plates, or $20,000+ in new rig not to mention the torn sails that come down with it?
MSC and Mcmaster have great deals and they are no harbor freight, but they won't supply you with PSC 37 chain plates.
20 years of hard sailing and salt water might just cost a few bucks to maintain. But the maintenance cost is far less than the replacement cost.
