Not sure why the the aluminum failed. It sounds like it became an anode somehow.
In 2015, I replaced our pedestal bolts and nuts with aluminum ones from Edson. On our model, the hex head of the bolt, sits in a hex sided well in the pedestal base so it doesn't turn. You tighten the nuts from below. The old bolts might have been reused, but something about them worried me, so I chose to use new bolts and nuts. I learned later that McMaster-Carr has both aluminum and stainless which you can get next day, so you may want to compare prices.
