Hello I have a 69 Caprice with the Comforton system I just finished rebuilding. I am looking for some details or pictures of the drivers side vent and ducting that comes out under the steering column. The vent I have has a square end where the duct tube connects and the PO seems to have duct taped the hose to it. I would like to know how it came from the factory. I would really appreciate any feed back on this as I haven't found any details.
