Default Vacuum Heat Controls

I am helping a friend figure out the vacuum routing on a 1969 Grand Prix. He got the car disassembled and is now putting it back together. It is a heat only no A/C. This is what we have. Is it everything? Any help, diagrams or pictures would be helpful. Thanks.

Just add the hoses and a check valve in the engine vacuum line.
