Tanks for overflow and window squirter

Currently the radiator overflow tank appears to be some aftermarket thing, and is mounted in place of the Wiper fluid tank. Wiper tank motor is present but tubes are MIA.

Would love to have any help telling me where the radiator tank is supposed to go, and what it should look like.
Also what does the wiper fluid tank look like and how does it mount to the tank motor?

I have looked for pictures but am not finding anything stock-looking.
Also of note, getting ready to replace radiator and the new radiator has overflow output on other side of cap, so it will now need to overflow to the left instead of the right (current)
