Re: Rear spring outer bolts/castle nut
The finish on the C bolts is more than black oxide, it has an organic base to it that provides much better (longer) corrosion protection. I would be very surprised to find any original chassis bolt in black oxide. Black phos, yes, and they rusted fast. At best they were a 96 hour salt spray bolt meaning in less that a year of normal use they were rusty.
