Been having problems with rebuilt compressors. Went through 2 from a Corvette parts business; just went through 1 from a "classic" car air/co shop. Seems the clutch assem. doesn't work, or the compressor leaks near the clutch area. I'm getting tired of pulling this thing off and re-doing everything every couple of months.  Anybody have any ideas...Thanks ("72" model).

It used to be you could get a reman compressor and never have any problems with it. These days, that's just not the case...
I have decided that NEW is the best way to go, at least on my vehicles. I changed the one on my 'Burban 3 times in as many months before I got tired of it, and bought a new Delco compressor. It's been working great for the past 6-7 years...

  I have been going to ask this question myself. I plan to take the entire system out just to clean the dead mice, leaves, old pennies, buisness cards and who knows what else out of the condenser/ fan area. Saw a "To Do" article in one of the VETTE mags I get, and thought it might not be a bad idea, seeing I have most of the engine bay empty any how.  Any thoughts for the process.   THANKS  Mark

The problem with reman or new for that matter is shelf life. New 72 model OE compressors have been discontinued. Not sure how long ago. So if you were to find one its hard to tell how long its been stored. A compressor as a rule should have the clutch rotated every so often to lube the moving parts inside. If its stored it should be sitting with the clutch facing down to keep the oil towards the seals. I have had new Delphi units crap out on me as well as remans. However if I have a choice I go with new.

the A6 compressors new or rebuilt all leak oil from the front seal, its the nature of the beast, if you got the extra money go the extra mile and go with the new style Sanden -Sony setup, takes less HP, less overheating problems.

How hard is this job to install the compressor and where can I buy one? I bought a 78 and it had NO AC system on the car.... and Dallas gets HOT in the summer.

Well, that's why they invented T-Tops I guess. The next best thing to a convertible Big smile. None of the A/C units works in our vettes and I can't afford to fight it so it's, off with the tops and off we go Clap.

Hmmmm Sorry to read this. My 74 has had the AC removed before I bought it. I didn't mind much living in Michigan but now I live in Tennessee and it's a wee bit hotter here. I have seen ads for insulating material. If I can stop the heat build up on my feet I might not replace the air.
What if you install a newer style compressor? What would be recommended for that?

Stopping the heat at your feet is an easy job.  you can purchase a valve from Napa and put that in the hose that will stop the hot water from being in your heater core.  Which it is even if the heater is off.  I have done this I know the part numbers are in a old post.  Let me see if I can find it. 

As far as air conditioning systems go if you need all of most of it.  There is at least one guy who belongs to this registry that been restoring corvette.  The ones he gets that are parts cars may have what you need.  I have gotten a number of things that I did not figure to ever get like t-tops for my 82 CE.

This is the info you need on the shut-off valves.  Just one does not help as much as the two because the heat migrates up the water in the open hose. You only need to close them in the spring and then open them in the fall, not much trouble at all.
 
I put mine so you can get at both from the engine compartment.
 
Part numbers for the valves at NAPA:
3/4 inch 660-1413 
5/8 inch 660-1414

Thanks for the info on the shut-offs. I will pick them up today . That's a good tip. I am still going to put the heat shield insulation under the carpet. And maybe the firewall.

I still want to replace the air but if everyone has failures with the OEM equipment I think it best to upgrade to a newer compressor. I wonder what all you need to change to do that. Brackets, etc. I have to replace it all anyway so might as well upgrade.

Some info!   Purchased 3 months ago a new AC Delco compresser from, RIGHTNOW auto parts.com.  Paid 190.80 with free shipping.  Price at the Chevy dealer was 400.00.  The compresser is the same size but the clutch head is smaller and more efficient.  Must check all thread holes, as they are metric!  Easy install, don't forget to add your oil before bolting your line on.
