Installed the wiper motor. Newport model 4753CCT on my 1950 3100
It clears the choke cable, and looks like it will clear an original radio.
Had to adjust the park to keep the wiper arms from binding. I also got a couple of longer 10/32 screws for the mounting location.
Can't test the sweep yet, windshield is not installed.
Working on modifying the switch to accept original type knob.
here are a few pic's
