Need complete wiper system for a 50 Mercury..

I have a 1950 Mercury with no windsheild wiper system . Car is painted so can't do a lot of outside work. I realize two holes will have to be drilled. Wondering what after maket system will work?.

 

Just did a quick google on your behalf..... you'll be wanting a cable drive system most likely, there's a ton of them out there .......if you want used to save bucks, some 50's 60's pommiemobiles had cable units.
If you are happy to have just p***enger side wiper, even more options for single motor, even 2spd, east to fit stuff.
