What spark plugs, wires and cap for a stock '71 318?

Since I have the Mopar Performance electronic ignition (kit from Mancini) would I purchase a cap and rotor for a production car that came, from the factory, with electronic ignition? If so, what was the first year for electronic ignition a factory standard (I believe '72 was the 1st year for electronic ignition for Mopar)?
The caps for all of those interchange.
The only Chrysler cap that will be different is if you looked up one that came with dual point Prestolite (never sold on a 318, so you're safe).
It has a spring loaded carbon button to contact the rotor and it won't clip in to the Chrysler built housing.
