I am looking to replace the alternator in my '74 Charger with a 440 to freshen up the engine compartment, and would like to keep it looking original. Car has factory A/C, tach and radio, and being a '74 it has electronic ignition. No other power options.

What would be the minimum amps advisable for these options, and also, how many amps would be recommended? Is the factory unit a 65 amp?

What year did the square-back come out? Was it '72?

If anyone could shed some light on which alternator should be used, it would be much appreciated!
