This buy it now listing is for one NOS Hose Tee for the Wipers of many WW2 vehicles. This is an extremely hard to find part.  I have included a picture from a TM-9 showing the location of this part. It is located in between the 2 "C" identification letters.  This fits on ANY Open cab WW2 vehicles, including the Diamond T, GMC, Dodge, Dodge M37, GPA, etc.
