1968 SS Doors

From what I understand

:) ok lets try again... From what I understand the SS Barracuda and Darts had acid dipped doors. Not lightweight steel skins, like the front bumper was lightweight steel, not acid dipped.

Question: Was the entire door assembly dipped, or just the door panel?

The inner construction may instead have seen a major cheese job, since there were no window mechanism... is my thinking, since I have no O-car around to examine...
Thanks
