Yeah, I am over 3 year removed from starting my project and it is getting hard to push forward much less recall how things came apart. I bagged and tagged hardware but when I go back to use it I find I am not happy with the condition so I am primarily using the old hardware to define the features required for replacement hardware.
That is the same decision I came to on my 53. I made the switch to all stainless because of the condition of them. Some of the stainless bolts I polished the heads also, not a slick mirror finish but shiny.
