I can't find a rebuilt compressor I can trust. I found a NOS AC Delco for $350. I can have my original overhauled in Tampa from Classic Auto Air Mfg. for $325. plus another $100 to recalibrate my POA valve. Is this just expense or is it me?

I checked with my local Carquest store today $125.00 I got him down to 105 I'm pretty good friends with these guys but they still have to make living. You may try CQ.

Finding good reman A6 compressors is getting harder every day.
There are, I believe, new ones being produced and are about $350. There is also a bolt on Sanden replacement that is fairly new on the market. (No mounting, hose changes).

I've seen new A6s and the Sanden replacements mentioned on their forum. I don't think they're listed on the website yet.

$325 for a good quality overhaul with a warranty isn't a bad price. It just looks high compared to the price of cheap remans available at some places. Find out if they use a double lip shaft seal instead of the old type ceramic seal. This upgrade is very common in the MVAC industry and eliminates oil slinging.

$100 to calibrate the POA is good if they know how to do it and you don't. :D
You can test and calibrate it yourself. Here's an article:
