-I have a factory AC '67 conv. I need all of the engine compartment stuff and I have all the inside stuff.

So I'll be needing compressor, condensor, evap plus firewall box and hoses, drier, exp valve, etc. The total cost for all that stuff (rebuilt and repro stuff)would be around the same as buying a vintage air system.

Question is, would it be better to go back original with salvage/repro and rebuilt stuff? Or just stick a vintage air system in it? Not sure exactly how the vintage air stuff works with my controls and wiring harnesses, etc. Is it just plug and play? If so all new for about the same price is pretty attractive.

And this is not an all original car, Its just going to be a nice daily driver quality.

I have a '70 with the factory 4 Seasons ac which I did refurbish and update to R134 when I restored my car. In addition I have installed Vintage Air and Southern Air units in several cars.

The only difference between factory and aftermarket that you will notice is that the factory unit allows you to vent fresh air into the car and heat or cool this air. The aftermarket units do not have this option.

The aftermarket units are meant to fit under the dash, so most likely you will have to fit a smaller liner in your glove box. They operate like a modern car with a cycling clutch, meaning you will have to install a new Sanden-type compressor in place of the GM A-6 style. You will need new controls (which most manufacturer's sell) because your factory selector controls are vacuum based and the new units don't use that.

My observations, based upon installation of aftermarket units in big and small cars, is that will work ok in a big car but not as good as the factory units work. That is because the aftermarket units use a smaller evaporator core and a smaller condenser. Since the idea is to cool as much air as possible and get the most volume of cold air into the car, the factory unit is better at that.

I hope you find this info useful.

Thanks!

I do have access to a few AC 67's but most of the components look pretty trashed. Especially the condensers. I have all the inside stuff already, but no evap box on the firewall. I'm not sure yet what to do. I might price the salvage evap box and some other components but I'm pretty sure it will cost more to go stock than to buy a kit from vintage air or similar. Mainly because all the new parts I'd need are about $300 each (comp, evap, condenser) plus hoses, etc.

Thanks for confirming I did the right thing. My car is a bit different. I restomodded a 94 LT1 into my 68. I had it converted to r134. The final cost of parts and labor was a touch under a Vintage Air set up. I would think a Vintage Air would be good to install in a non-ac car rather than one with the factory ac already present.

Good to know on cost. The nice thing about Vintage or similar is that the install is much cleaner and modern. I'm still undecided.

Where did you buy your new or rebuilt components? The rebuilt compressors and other components I found were pretty pricey, around $300 each if I remember right.

I'm probably a bit late to the party again but I've been looking on the internet for the same items for my factory 67 A/C and found a couple of places who do said items your are after.

Depending on where you live there's a place in Tampa, Florida (below)

And a place in Graham Texas (below)

Have dealt with the first one and found them good for what I wanted at the time but not A/C stuff.
The second is an unknown.

Cheers,
Chris.

I found the used compressor on LS1 Tech, along with a few other items I needed. I had to go with a custom AC bracket that mounts the compressor on the driver side of the engine. Believe it or not, I found a muffler shop in town that does all kinds of hot rod work. I had them do the install. They wired up everything like is supposed to be, even pinning in a wire in the existing LT1 wiring harness. It was a great job and looks factory.
