Hi All My AC Compressor is leaking oil and R12 out the front seal.

Thanks Joe

Replacement A6 compressors are available from NAPA & other similar parts retailers for between $250 & $300. They are still manufactured new, but are expensive. If your compressor is otherwise in good condition, replace the seal. The front seal is ceramic on all of them. Excellent instructions are here:

Not really. A-6 compressors haven't been manufactured new for over 25 years, and the "re-manufactured" ones aren't; they've had a light rebuild (just seals and cosmetics), and most of them use the old standard carbon shaft seal, not the newer (and more expensive) ceramic seal.
As for rebuilts, despite 4 Seasons earlier reputation for being problematic I'm running two of their rebuilts on two cars with no trouble. They use new ceramic seals. It is true that the earlier A5's (not to my knowlege used in Corvettes) are hermetic units with no flange and cannot be rebuilt short of a clutch change and re-paint. I have one of these too, on a 60 Buick.
Not looking to start an argument, I have 5 GM cars with factory air and spend a lot of time keeping them all working.

New a-6 compressors are available, but GM/Fridgeaire/Harrison isn't still making them. Not certain who the manufacturer currently is, but the new ones have METRIC threads and dimensions. I guess you could think of them as a reproduction of the original.
AC DELCO or Delphi listed them as available a few years ago.....not certain they are still being made.....or if the new ones being sold today are from older inventory??
The cost of a new one is about $500.
Not certain about what seals the new type a6 has. A carbon/ceramic seal should be available for replacement or retrofit if needed. This seal has been available since the 1970's. Very early a6 used a seal with a steel face.....and these never worked well.

It was Harrison until recently, someone must have licensed them. These boat anchors were used by so many cars (Ford in the 70's, Jaguar & Rolls Royce/Bentley, that it probably pays to keep producing them. Same with the old Yorks used in almost everything (including over the road trucks) except GM & Chrysler cars from the 60's-70's, these are still made too.
I see someone has an aluminum A6 dimensioned rotary out now, half the weight & load and look like they would work well in a non-show driver.
The old seals threw a lot of oil around as you Corvette guys already know! (I laughed when I first saw that shield mounted on the front of a compressor). The ceramics in the A6's I'm running now do far less of that. They may be heavy & suck power, but those wobble plate A6's make mighty cold air!

I did some searching and found this. Company is located in Texas, but not certain that is where everything is manufacturered. FWIW.

New A6 Compressors
The correct model is 51-16262A which has a 5.625" pulley and the coil connector clocked at 10:00. As Larry noted, it has metric threads.
This is the closest you're going to get in a new A6 style compressor, based on my research.
If your leaky compressor is original, the tools/parts to replace the seal are under $200 and the procedure is well documented in Jeff's sticky.
That's how I would go.

Thank you all
I'm stilling looking and have time.
I like to get a new one with the carbon/ceramic seal.
Its easy just to change it out then change the seal.
