A/C System
So I'm needing some advice. I have a 71 cheyenne super with factory air. The system is complete. The only thing I've replaced is the compressor which was missing when I bought the truck. I'm debating fixing the factory air system or replacing it with a vintage air system. Any thoughts?

Re: A/C System
I like similar-to-factory air. I went with Original Air. I want a functional glove box and functional engine compartment evaporator casing and blower. Here is my experience. https://67-72chevytrucks.com/vboard/...d.php?t=790246

Re: A/C System
In my experience, the compressor is the weak link in the factory system.
If you truck is mostly original I would try to retain the factory system and possibly convert to a new Sanden compressor. The vintage air will get rid of the fiberglass box on the firewall and everything packages nicely under the dash. The vintage air system I had worked great and I will definitely install again, but not in an 'original' truck. |

Re: A/C System
Kind of in the same boat, My compressor went out in mine and on the fence of rebuilding the stock compressor or buying a new compressor. Really want to keep the factory look.
This is the compressor I’m looking at https://www.oldairproducts.com/produ...=p124208-o2335

Re: A/C System
I always go with factory AC when it’s complete. I use an A12 replacement compressor which fits the factory brackets. I use R12 as the system is designed for and have zero problems that way and enjoy ice cold air in 110 degree heat.

Re: A/C System
I use R12 in all of my vintage vehicles. It's still fairly easy to locate.

Re: A/C System
^ I bought a 30# tank at Pep Boys just before one had to have a license to buy it. I went to CostCo just before that, only to find that some guy had just bought the last two pallets. My tank is pretty much empty after all those years. Where are people finding it, these days?

Re: A/C System
Carlisle always has some available. I have my EPA 609 cert, but nobody ever requires me to show it when purchasing it there. I have quite a few of the 14 oz cans right now to top off the systems if needed.

Re: A/C System
I converted my stock a/c over to a swap meet 605 compressor, new ebay condensor and late model evaporator. Blows 45* at vent outlets easy to do a little mod here and there but still works great allso purchased an a/ac line kit from old air .Going on 3 years not 1 problem
