1965 Dodge Dart Charger

Started out with the prop shaft. My old one have a bunch of markings so I changed with my brother in law.

This shaft has no marking and has the front yoke made by Detroit with the DPCD markings. This shaft has orginally been painted. Under all the grease,undercoating and dirt is the back paint. What I know of is that they were natural in finish. So the question is; was the prop shaft painted back in 1965? Any help is very much appriciated.

The rear U/joint have a connection between each side. I'm not sure of the reason for that.
