Emission and vacuum hose schematic diagrams?

Hello, I am an owner of 1979 Buick Regal Ltd. I recently took all parts off of the engine down to the block to strip it and re-paint it. Well all of that is done now and I have about 85% of everything back together. The problem I am having is where to put all the small vacuum hoses, I know where some of them are but I need a true diagram and cannot find one for the life of me. Please let me know where I can find one or if there is any database that can help me. Thank You.
