I use my 67 quite a bit in the summer season. The old A6 started growling so of course I unplugged it. I'm looking at the new style aluminum cased ones for some of the benefits they offer. I will be sticking with R12 as I have plenty. Can I get some comments on switching over? Thanks, Al W.

I'm running a Sanden compressor on my aftermarket AC unit. Running R134. It's been in there for a while. Their are many different inlet outlet configurations.
Most of the Aftermarket AC Mfg's use them. You might try looking into Vintage Air and Classic Auto Air as they sell individual parts . Hers a Link ..you could cal them and ask about your needs . https://www.classicautoair.com/shop/...ioning-system/
I have a Sanden compressor in both my 66 and 68 small block coupes. The 66 is a Vintage Air system with R-134A. It cools really well here in Florida. Most of the time I cannot put it on high as it numbs my hands on long drives. My 68 has a factory system with a Sanden compressor with R-12. I also updated the fan to move more air. It also works very well.The Sanden compressor cycles off and on, so, I added a selonoid for stop and go traffic to keep the idle up while the compressor is on. I would ask Larry (Powerhouse or Powershift) for his opinion. He is the A/C guy on the forum. Jerry
Many of us have sent our A6 compressors to Dom in Southern CA. He’s done two for me and they both run great! Larry told me about Dom and I’m very happy he did.
The way I understand it is that modern compressors are rated at lower flowrates and are designed to work with matched, high capacity condensers. Using a modern compressor with an antique condenser will result in less cooling capacity.
Yes............Dom is the guy. We are very lucky to have him available for us. But just recently he had more family health issues, and I am not certain how this is affecting his A6 rebuilding. But having him rebuild the compressor is like buying a new one.
Since you mentioned "growling" of the compressor, do you know what the oil level is?? Dom has told us how to check this in the car. I can summarize if Dom is not around.
Other options that are easy are: buy a new A6 from ALMA Products in Michigan. Metric threads, but otherwise looks as original with both internal and front seal improvements to "modern" specs. Or the Pro6Ten compressor that Old Air Products in Texas sells. A "drop in" for the A6 with all the advantages of a modern unit.
In summary: three choices: Dom, Alma, or Pro6Ten. But do check the oil in the A6 first. It can be added without discharging the refrigerant.......although doing it without pressure on the system is probably best.
Mike Geary is also a great knowledge and experience base for AC on this forum. You could PM him if he doesn't respond to this thread.

Picture of my Pro6ten compressor. Uses all the factory original hookups and hoses. I added the front shield (probably not necessary on this unit) to protect underside of hood from any oil leaks. Works like a charm!!

Larry
Larry is too kind -- I'm just a guy who had to study up on A/C when I bought a '65 A/C convertible in Tucson.
But, as usual, I agree with Larry's options. If you don't mind the different look of the Pro6Ten, I'd go with it. (at least it doesn't look like a Jarvik artificial heart) Less HP drain on the motor, and maybe no significant idle drop.
If you've got a really correct A6 core (dated rear head, early pulley, etc) , I'd touch base with Dom to see if he's taking in work presently. He's only a couple of hundred bucks more than a new Alma Products -APCO Air unit.
