Rebuild or Replace

Year: 1968
Make: Chevrolet
Model: Camaro
Engine Size: 327
Refrigerant Type: R12
Country of Origin: United States

Hi Guys,
I'm really glad I found your forum. I have a stock 1968 Chevrolet Camaro with a 327 and stock factory air conditioning. Everything was working fine and is original except it looks like the evaporator has been replaced at some point. The system was working fine and about six months ago the compressor seized up. I have access to R12 to keep the system running. My question to you fellows is do I keep this original system running and fix it as it needs with the stock style compressor or should I upgrade to a Sanden style compressor (I heard they are much more efficient than the original Harrison's) and keep the R12 or switch to R134A, or replace the whole system with one of the aftermarket air conditioning kits sold by Vintage Air or Classic Air?
I do have experience with refrigerated sea water systems running R22 so I am not a complete greenhorn. I also don't have a problem taking the car to a shop if I have to. And I certainly would not have a problem buying any parts or supplies needed through the forums sponsoring company.
I am in Alaska fishing and come into port every week to offload our catch and that is when I can get on the internet. I am trying to get some preliminary information gathered so when I get home I have a plan for repairs. Thanks much. Craig J.

Keep the system stock! new parts are readily (?) available. New A6 compressors are still plentiful. Stay with R12. This is just my opinion, but I feel that the A6/poa/txv system was about as good as it ever got for car a/c systems. But then, the newest car a/c I ever worked on is my sister's 76 Corvette, and my 67 Impala cools just fine here in central Arizona.

Back in the dark ages I was a Machinists Mate in the US Navy. Had the AC&R job code. All of our a/c equipment used 12 or 22 with water reg valves. Constant discharge pressure, constant liquid line temp. Those were the days! Retired in 1990. Don't have a clue what the systems are like now.

Keep that camaro running.

Thank you for the reply. I was hoping that would be the recommendation. It would sure save a lot of work and money. I want to keep the car as stock as possible but still have it comfortable. Craig J.
