1973 c60 vacuum diagram

I am new here. Hoping for some good advice. I have a 73 C60 that I am having hydrvac issues with. It's eating break fluid without any leaks. I figure I will need to rebuild the unit or buy a replacement. While investigating I found that there is a vacuum line under the drivers door that dead ends into what looks like a filter. The line has broken off. I have no idea what the device does but I need to either replace it with a new one or reengineer a suitable substitute. My two speed will shift down but not up so I am wondering if this is effecting vacuum and causing that issue. A vacuum diagram would be nice. As far as the hydrovac issue I am thinking that the brake fluid is either going into the vacuum side or pooling up in the booster it's self. Thanks

Answering my own question here. I did research a year ago and could not find the information that I needed. Fortunately this time I was able to find a couple of good resources that I will link here. I still need to find a rebuild kit but I know more now than I did.
