Underdash A/C

[tutone]

Talked to the vintage air guys at Louisville Saturday and no-one seemed interested in pointing me towards a unit that fits under dash on my non air 72. My heater works great as well as defrost and replacing that is out of the question. I have seen the old mark 4 units , but just not in 30 years or so. Have any of you guys got a picture, for reference ,of a properly mounted under dash unit in your truck? I would like to see how far they stick out and any feed back is appreciated. There isn't a ton of room from what I see to put one. Thanks.
