Windshield washer nozzle part number

[leftrightother]

I have an 07 GMC sierra (old Body style) and on the right wiper arm there is only 1 washer nozzle that covers only half of that side of the windshield. I bought the truck used and think that someone must have replaced the P/S nozzles because on the drivers side there are 2. The one that is on the P/S also does not fit the arm properly.

Does anyone know the part number for the 2 nozzles on the passager side?
