Vacuum line that connects to windshield wiper

[Daba]

Does anyone have a routing diagram of the vacuum line that connects to the windshield wiper. I’m working on a 1931 three window four-door.
Thanks Daba

No Diagram but I can tell you that it goes in this order:

-manifold to firewall (steel tube)
-firewall up the passenger A pillar (steel tube)
-the 90 degree bend is at the top of the pillar
-From the bend a rubber hose connects to the wiper motor. The hose is held to the top of the windshield frame with the same clips that hold the frame in place.
the rubber tube then goes through holes in the frame either to the outside and to the wiper motor.
