What else I need to run AC in my Duster? I got the compressor with mounting bracket and hoses and heater core, what else is missing?

I wish to get all things needed before installing it.

You need the condenser and the evaporator. The evaporator goes in front of the radiator and the condensor goes in/under the dash. Do you ave the auxilliary fan and ductwork to run the A/C? That is usually part of the evaporator unit.

Condenser and evaporator.....none of them I got, auxiliary fan where it goes? (also don´t have it), ductwork are the hoses that runs from the compressor to the heater core? if yes I have them.

Condenser, what it does? regulate heat/cold and air flow? or that can be regulated from the defroster controls of the heater?

Someone got pics of their engines with AC?? please post some pics so I can get a idea of how things are installed.

Well, what type of system are you adding? I have seen at least three different systems in early 70s a-bodies. Are you adding a factory system? Are you adding an add-on dealer installed system? Are you adding an aftermarket system from someplace like Sears?

You're going to need the controls themselves from an A/C car, also...

What year are you working on? I'm adding "factory air" to my 65 Dart convertible with everything pirated from a 66 Dart. Besides all the parts previously mentioned, I've had to change portions of the firewall for the blower motor (they're larger than non-AC cars) and add specifically placed cut-outs for the AC lines and mounting holes for the underdash unit. If you're doing a "factory AC" conversion, the donor car would be extremely helpful to have. I also had to locate the 65-specific heater/AC control panel.

Evaporator is under/in the dash. Condenser is in front of the radiator. It is likely just best to buy a complete system from Classic Air. It comes with instructions and cost about $1300. On a slant 6 you will have fan clearance problems on an A-body but these can be worked out with fan spacers or electric fans.
Do a search for Classic Air and Bren67Cuda904

I´m getting the AC parts from a friends Volare 82 (big and box like car), he removed the AC ´cause radiator of heater core broke and cost to much for change it (300 dollars!), so he is willing to give me those parts to pay me a debt, but that´s all he got from the engine bay.

Don´t know is he got the evaporator inside this dash or not. Sorry for the lack of information at the start of topic andor in this one, but getting AC in my car is a exciting idea

Well, the Volare A/C parts that go in the dahs won't be adaptable to your car without a great deal of fabrication. Here's why: in any a/c system you have the compressor to compress the gas, the condensormounted in front of the radiator to cool the gas, and the evaporator under the dash to cool theair blown over/through it and out the vents. On nearly all A-bodies the evaporator and fan and ductwork was all contained in a separate system from the heater and vents of the car and could be unbolted all in one piece. A/C systems in A-bodies had two fans and two sets of vents and ducts- one for the heater and fresh air vent systems and another or the A/C system. In the Volare the A/C components were integrated into the regular heater and vent systems. Another difference is that the Volare A/C system used vacuum to control the air doors in the vents system to direct the air flow. Most A bodies used cables to direct the air flow and the heater doors. The two systems are not easily interchangeable.

The good news is that you can fabricate attachments to run the factory compressor and hoses from the Volare to an aftermarket under dash evaporator.

Avenger2040 - I've got an underdash AC unit as removed from a 72 Valiant that you're welcome to have for free - just pay the shipping from VA. If you don't want it, same deal goes for anyone else who would like to have it.

Well the heater core is original part of the Duster, so meaby there we remove a problem, but the rest is still the problem, I will try to take some pics of the parts I got already.

Not correct. Factory installed A/C was an "integrated" system, from at least 1965 on (don't know about earlier). That means the A/C and heater are in the same case and up in the dash, bolted to the firewall.
The "dealer installed and after market units are "split" systems. With these the A/c evaporator was mounted under the dash (knee knocker style) and had its own separate controls and blower motor.


Also the heater only "A" bodies used cable controls for temp and air distribution. The factory A/C cars used pushbutton/vacuum air distribution and a cable temp control.

The earlier a-body factory systems, at least through 69 appeared to be split systems because the registers were contained in an add-on duct and plenum mounted below the dash but they were indeed integrated systems.

Growing older is unavoidable but growing up is strictly optional.

Then it looks like I will not need that extra fan, what is good for me.

My son's '74 Dart Sport has factory A/C. The heater/air conditioning control switch mounts in the dash, just above the radio. It has vacuum lines coming off the back to switch from fan, heater, A/C, etc. It has one cable to operate the cool/heat blend door. Also, fan control wiring attaches to terminals on the back.

Here is a list of parts:
Dash control switch
Under-dash heater/air conditioning box (contains evaporator and heater core)
Expansion valve
Receiver drier
Compressor and brackets
Evaporator sealing plate (where hoses attach at firewall)
Vacuum reservoir (black plastic can-looking thing on passenger inner fender)
Suction line
Discharge line
Water control valve (operates water flow to heater core)
Two heater hoses
Blower fan

There might be a few other things, but that is a fairly comprehensive list.
