Is there Factory looking a/c kit for my 65 Cuda?

Depends on your engine, how late you consider factory (76 Dart, 80 Aspen/Volare OK?), and whether you are talking under-hood, cabin, or both.

In 1965, factory AC was a different firewall, so hard to meet that standard. Factory might also be considered a dealer-installed unit, designed by Chrysler. My 65 Dart had a Tecumseh compressor, which might have been dealer-installed. I am not putting that monster beast back. I think many used a York instead (my 65 Newport has one). AC was still new in 1965 and quickly becoming desired, so there were many quickie solutions.
