HVAC question

My 1973 Newport has a small issue. I’m planning on getting the AC back online but it seems that my temperature adjustment cable isn’t connected to my lever inside the car. I’m not sure if it’s broken or not. There is no drag on the lever which tells me it’s not connected somehow.

Is there a way to reconnect the cable and in the worst case scenario, is the cable itself replaceable?
