Restore factory ac or go aftermarket

I have dug into it a little bit more. Its looking like the dash controls aren't operating. The fan switch isn't turning on the fan and the push buttons don't affect the dampers or anything. Not sure if they will without the a/c compressor hooked up, but I figured they would still work. I am thinking of just running a complete aftermarket system with electronic controls and just get rid of the vacuum lines and redo all the electrical since I have found some re ran and burn circuits under the dash that need to be fixed.

Right now, I'm going to just roll the windows down and see how much of the summer heat I can take. I have decided either swapping in an overdrive or taller rear gears is a higher priority for this daily driver.
