Could anyone tell me what the correct measurement/dimensions for the brass intake fitting are that should allow me to attach the wiper hose?

Also- any idea where I could find the correct one? Been looking for some time, but it doesn't seem like the usual vendors carry this.

My wiper hose got cut off pretty close to the cowl - the outside of the hose measures 1/16.

The thread of my current brass fitting (that doesn't have a port for the wiper hose) appears to measure 1/64.

I have attached pics of both.
