As the weather warms up, we inevitably turn to the lousy dash air conditioning issue.
Our '75 has had a fair amount of work done and the a/c works, but not well.
I've seen a number of potential fixes, the two that appeal most are
fresh air intakes and/or more direct airflow from the existing a/c such
as this:

or possibly the Vintage Air add-on unit such as this:

The ducting rework solution seems pretty straightforward, but I'm curious
about the vintage air units. As I understand it, the add-on unit in the link
is only a small part of the what's required in materials, and it's a pretty
labor-intensive modification that needs some specialized a/c knowledge
and tools.
Has anybody here had the vintage-air unit added? Did you install it
yourself or have it installed? How well does it work, and what was
the final cost in parts/labor?
Ideas appreciated.
thanks,
