Late model A/C compressor in 70 Dart?

I've got a 97 360 Magnum in my 70 Dart with the A/C compressor and serpentine belt assy from the late model, the car has the factory A/C from 1970, I want to hook the late model compressor up to the early suitcase. I need to get a condenser/dryer and have the hoses made up. Will I have any trouble getting this done? Is there anything special I should know about... condenser, orifice, hose fittings, etc.? I intend to set it up and have a professional charge it up.
Thanks,
Doug
