Default Needed,vacuum diagram,351M,,5.8,,1978 Mercury

Hello,not sure if I am the correct place. I need a vacuum diagram for a 1978 Mercury Grand Marquis with 351M,,5.8 Liter motor. The sticker on the hood is missing so I cannot see the routing and I seem to be having a hard time time with the lines. My father took the intake off to replace the intake gasket,and I mentioned to him to take a picture of the motor and the routing before taking this apart,and of course,he did not. I have a idea where they go by the bends,but not sure where the distributor vacuum goes,to the ( Distributor Modulator Valve ) if that is what it is called,or to the carburetor,or from the carb to the valve then to the distributor? Any help WILL BE APPRECIATED. Thanks dad,gotta love em,Thanks,Mark,,,,
