Heating & AC / Vacuum Circuits / 1975 K10 Silverado w/AC

[motorbreath777]

Hey Everybody,

I've had no defrost in my truck since I bought it this July.  Moving back into the rainy seasons I've set out to fix this.  With my dash torn apart, I can more or less see what's going on, and have managed to rig the control doors to give me defrost. 

Does anybody have the vacuum circuits for this truck available to post, so I can fix this correctly, and have some control from the driver's seat (or know where I can find them)?  Between the 74 FSM, and the 76 supplement I have access to -- no dice... any/all help is appreciated.

Thank You
