Anyone have one of these? Let me know condition and price. Trying to resurrect my AC for summer. Thanks in advance!

Benjamin,
A 75 would have a VIR. That is one vessel device that contains the receiver, site glass, expansion valve, desiccant, and POA valve.  They used to be reasonable, so when I recently stripped the threads trying to fix a leak on the oil return line of my '76 I was surprised to learn that they seem to have disappeared from the market place.  You can have one rebuilt, and the going price seems to be in the neighborhood of $350.00.  Needless to say, I rebuilt one that I had and I am glad when they were available I scrounged up a bunch of the internal parts.

I run an Old Air Products "VIR Eliminator" kit on my '74.  Another option.

Did you make any other modifications? I've read that the eliminator can cause issues for the compressor (something about cycling). If that's not an issue I may go that route.

The compressor does cycle with that kit.  Some say that the A6 compressor wasn't designed to cycle, but I haven't had any problems with it.  I'm about 2 years in -- drive the car ~1500 miles/year.
