I have just about completed installing new electric wiper motors in my '46. I wanted it to look original.
I purchased the motors from Jim Carter and removed the plastic housing and switch. I did a little rewiring to remove the built in wiper motor switch. I then took the vacuum motor controls and adapted them to an electric switch and faux mounted the remainder of the controls. I had to grind out the center chrome exterior anchor parts of the original wiper motors.
I have a little more cosmetic work to finish. If anyone wants the whole story let me know and I'll provide the details.
