Paul. That is great. Very much appreciated. On No. 9, it's the other nut on the Diff Mount Bracket (one is a castel nut and the other is hex). Thanks if you can help on that one.

The GM #125267 castle nut is zinc plated. The GM #3691530 lower shock nut is a gray phosphate. The lower rear shock retainer, GM #3714310, is natural steel.

By silver I me ether Zinc or Cadmium we would not know which was used in any part with doing an analyzes of the plating being used. So that is the conundrum to figure out.
