I'm painting the deck of 376 and have just finished removing all the deck hardware, including the tracks. And I can tell you removing the nuts from inside the toe rail was probably just as hard as it was for who ever put them there in the first place! However, inspecting the joint and top of rail has not uncovered any kind of stress or cracking. I figure if its held for 40 years, it will hold another 40. But if someone has a great idea on how to provide better backing than just using washers, I'm all ears.
