@qz16 - I am starting down the path of a full ground-up restoration of my '73 (sort of) 240Z. I've removed the dash and can now see the somewhat of a disaster the heater box and the AC system is and will be to restore. I like the compactness of the VintageAir Gen 2 Mini, however, buried in your description is the statement "Also, you need to seal off the cowl vent because there is no provision for the vintage air system to utilize that vent. The only fresh air vent system that you will have will come from the vents on the driver and passenger side which are controlled by individual mechanical cables.". The mini shows 3 oval outlets on the top. The right and left obviously get routed thru hoses to the right and left dash vents but why do you say there is no ability to use that middle vent? The original plastic piece that connects the metal center dash vent housing to the original heater box could be cut at 45 degrees and reglued so the outlet faces downwards at 90 degrees and should be pointing, pretty much, at the middle outlet. I'm making assumptions here based on your photos of the unit's placement as you didn't include any photos of how you connected up the hoses nor did you talk about it other than the above referenced statement. If you didn't make use of that middle dash vent what did you do with that middle port on the Gen 2?
