It was a factory option code J55 on buildsheet. The factory did it after most components were installed like brake/fuel lines and fuel tank, etc. My Challenger vert was undercoated only on the drivers side, someone was asleep on the job back in Sept 1969...I know the trend is to primer restore without undercoating but most original cars I have seen did indeed have undercoating although my Duster is bare.
