Help please - rebuilding original AC car w/o AC

The vacuum control would still be needed too select heater vs defrost. That is vacuum actuated, not mechanical. I did this very thing on my 68 Dart. I just cut the AC portion of the box off and chucked it. Saved a ton of weight too. I left the majority of the actuators so the cabin fresh air door, defrost and heater hose valve still operate as intended with vacuum.
