With the little nozzles right by the wiper posts, your car is a '65 or earlier. This means the little black wire harnessed with your generator wires is the washer pump power.
Get a gorgeous, barely used bottle and pump (+ bracket) from the passenger side, rear tire compartment in a 240 wagon. The bracket won't mount perfect on the passenger side inner fender, but while you are drilling and adding screws, add a ground wire.
Should be pretty easy to do. Third click out on your wiper switch is the pump.
Best,
Shayne.
