New to the forum...looking for anyone that has a 69 SS or Caprice with the Comfortron system and factory AC. I am trying to identify the parts needed for the vent under the steering column and supply hose that runs under the dash to the main HVAC box. Any pictures under the dash or a parts illustration of that item and the hose that is connected to it would be great. This is for a 69 model year big block car.
