My I chime in here I have a 48 Station Sedan which I have added AC. It has proven to be quite a project.
1st you need to decide what it will take to change the car over to 12 volts as no equipment is available for 6 volt. New alternator and mounting bracket, light bulbs, coil and change the starter over to 12 volt. If you have over drive you will need a voltage reducer to take care of it.
Next comes how to drive the compressor, as it is near impossible to find a 2-grove crank pulley that will work. I had a machine shop make a special 2-grove pulley for the alternator to drive the compressor.
Next is compressor mounting you will have to shop fab a bracket as no one makes one for the Packard 8.
Next is what kind of evaporator, under dash or behind dashes, just cooling or heat and cool. If you use an under dash unit, then what do you do about the heat vent controls. If you use a behind dash unit you have to remove the heater and use a combination heat cool unit and rework the glove box for clearance, which is what I did.
And now the biggest one is keeping the engine from over heating. The 48-50 Packard 8 engines are known to be subject to overheating. You will have to use either an under mount condenser with an electric fan or one mounted in front of the radiator then you will have to change the fan blade to a 6-blade high volume blade with an adapter and you may possibly have to change the radiator. This is the problem, which I am still working on.
