Just wrapping up the full restoration on my 1970 d100 and I’ve pulled my hood hinges off the shelf to prepare them to be installed.
Looking at them very closely, they appear to have never been painted and are some kind of coating on the bare metal.
Can someone set me straight on what the factory correct finish should be on these hinges?
We’re they painted body colour, or left bare?

Some were painted, most were bare. Depends on yr and model.

I thought it a black phophoric acid oxide treatment, characteristic of most of the bolts.

Bare of paint, not bare of treatment.

I have a kit with which to do that, but it takes an awful lot of distilled water. Used to take my bolts and small parts to a plating house in LA where they'd do the whole batch in zinc chromate for about $50. Hell of a deal, but the enviro-not-so-greenies killed all that. Destroying the plating industry was one of the major moves they made to drive industry offshore and fatten Wall Street wallets at the expense of the people who built those industries. It worked too.

I bought my (early 65') Utiline from the original owner so was untouched or unmodified. The hinges are silver and appear to be electrolytic zinc.
