1965 Dodge Dart Charger

In the last MCG there was the article from Frank Badalson re the nuts that holds the carburatorto the manifold. On the hemi engine there were black phosphated pins and silver cad.

After I read the article I was so concerned to check out my own car.I have redone my nuts and washers for my car. But after checking out the original engine I have + some oldcar magazines from the early/mid sixties I found most cars had black phosphated pins, silver cad nuts and no washers!!!

Here is some pictures on how it looks.

So the question is; all you guys out there who has unrestored 273 HPs can you check if there was any washers and if the nuts are silver cad or black phosphated?? Thanks for the help.
