On our 71 142 my son and I used the evaporator/fan etc. from a junker to look stock in the car. However, everything else is new, including a Sandon compressor and an electric fan. I had some R12 left over so we made ours R12 compatible thinking at some point we would use R12. However other demands for the R12 convinced us to use a substitute, Duracool.

Vent temps get to about 40-45 degrees on a 90 degree day on the road. However, at idle in town rises to 55 or so. I tried going down hill at idle at 60 thinking it was air moving over the condensor but decided the compressor, expansion valve, or the wrong refrigerent is the problem. Now considering converting to 134A.

Going down the road the AC is fine for two people, but lacking with more people or town driving. But much better than nothing!!! I would be curious if there would be a possibility to obtain an updated evaportor that could be used with the rest of the under dash equipment.
