the factory wiper was a vacuum unit that was self contained above the windshield with just a hose running to it. i'm not sure if a second one on the passenger side was standard, or optional in 33. a dodge would be the same. i'm thinking they did not get mounted under the dash until the 40's ?
As far as I'm aware, most of the baseline cars, regardless of manufacturer, came with only a single wiper. A second was usually optional. I guess they didn't care if the passenger could see in a rainstorm.
I find that Rain-X does an excellent job of keeping the rain off the windshield.
