Installing A/C
#1
My 73 coupe originally had factory air. The previous owner was racing it, so everything was stripped out.  Wondering if it's possible/reasonable to re install factory air, or would aftermarket system be better. I'm not interested in staying stock, just cool.

The original works fine and should be able to find everything pretty easy. No bad issues with any of the components. Of course convert to new refrigerant.
Hope the PO did not just hack up your wiring to remove. If all the plugs are still there makes it neater and easier. The dash will need to come out to get everything in place again. I have a 72 vert parts car I might be able to get the system out maybe in the summer. Issues with neck now.

I am in the same boat except I am missing everything under the hood. everything inside the car is still there.

so over the holidays I purchased all the necessary parts to install ac under the hood. I am converting to sanden pump.
Anyways, I'll try to document the install process as much as I can
cheers

I haven't pulled the dash apart so I don't know what is or isn't there.  I don't even think there is a heater core as the hoses are not there.  I'm a little afraid to go in, actually...


 If I buy the original stuff, will it work with the new refrigerant ?  Also, most people like the "sanden style" compressers.  Thoughts?

Yes the original works with new refrigerant. I even went to the latest that is not sold in U.S. yet called Duracool. Takes way less just a little over one can to fill a dry vacuumed system. http://duracool.com/Duracool/distributionsales.html

You will use the new o-rings made for the new coolant. You can get vacuum pump and charging gages at Harbor Freight for less than a station will charge you to do the vac and fill.

Are the original AC hoses compatible with 134A refrigerant?

Yes the hoses are, but the original style seals are not. will need all new O-rings as mentioned above that are compatible with 134A

Are there any O-Rings under the dash that have to be changed out? If so, I suppose you have to remove the dash pad to get to them?
I need to convert mine to 134a. I have all the stuff, just havnt had time to get into it.

I do believe that the last connection point is in the engine bay at the firewall. I do not think there are any connections IE O-Rings inside the car.
