For your truck specifically I cannot say sir.
My 66 however has it.
The wiper fluid pump is integrated with the wiper motor, although the fluid resevour was mounted next to the radiator on the d-side of the engine compartment. Right next to the voltage regulator (of all smart things....)
I posted because I really liked your mapping all this out, I would have found it very useful about 8 months ago for my build.
