vacuum help for 429 please

I have a 1968 429 ci with a holley carb model number 9834. I am in the process of reinstalling the holley on the motor. When I received the carb and motor, the carb was not installed. I have been looking for a vacuum diagram to help me with the installation. I can not find a real good one that shows me what I need to connect. Does anyone have a diagram that they can share?
F1 truck is very vanilla, Power brakes, electric choke, C6 automatic.
Thanks in advance.

Just rebuilt my model 4160 750 holley for a 429 that originally came from a 70 tbird. It's in my 75 f100 4x4 now. The only vacuum line I have is the one from the metering plate to the vacuum advance on the dist. and the big line in the back to the pcv system.

Manifold vacuum, anywhere you can get it. Most power brake boosters take a 3/8" vacuum line and most of the time you run that to a fitting on the manifold.
