Vacuum Diagram Stock 72 Dart 318 2-bbl

I'm rebuilding the carb with the correct top. The replacement carb had a flat top. When I started rebuilding the original carb, one of the idle mixture screws snapped right off. So I'm blending the two carbs together.

Just trying to figure out where everything went. When I got the car most of the ECS ports were plugged and the carb vents as well. I'd like to get the vacuum system all correct before I start working on the Heater and AC controls.
Ok gotcha
