I'm adding air to a 66 New Yorker. The path of least resistance is to add a Vintage Air or Southern Air evaporator unit with a Sanden compressor and modern condenser. I can see the benefit of the modern compressor and condenser. But looking at the smaller sizes of the heater and A/C evaporator cores I'm wondering if I should think about rebuilding an original box and just upgrading the compressor and condenser. Any ideas about this?
