1966 Barracuda A/C question

Happy New Year to you and all the Members here!
my guess is seals and o-rings (are you keeping the V2 compressor?
you could take it to a shop and have them check it out with dye if you don't have a vacuum pump to check for holding vacuum. Compressor Pump seals, hoses and o-rings get brittle. condensers get leaky and corroded but usually the evaporator (if not packed with debris and leaves) isn't the culprit or is usually the last part to go. 67 evaporators will work if you have the tubes re-bent to match your 66 setup. I did mine, but I have a good 67 one that was re-done by a Air compressor shop and re soldered to the core for the wife' 66 dart for that configuration.

I have my own A/C tools to do the vacuum check, my thoughts exactly was prior to tearing it all apart was replacing all the seals, having the lines remade and trying it again I have removed most of the lines in the engine bay and the seals were dried out [I couldn't get to the fire wall ones Easley so those are for later]. I also have to find a dryer or have my original one repacked, long ago I thought I saw something about a company that could cut open the dryer and replace the dessicant and seal it up [weld?] again.
