I have a 1974 olds delta 88 royal convertable w/ a 350 rocket 4bbl and I was looking for the vaccum diagram for this engine.Can somebody give me a hand?

Hope someone kicks in here, but without the exact car/engine to copy from, or a shop manual or the emissions label, doubtful.

If someone has the same year of car with the same engine, please send me a picture of the vacuum lines or draw me a diagram. Thanks it would really help
