when did they go to electronic ignition?

Mopar was the first to offer electronic ignition standard. Just another useless fact.
I always thought 72 was the switch over year. Never saw a 71 with electronic.
Maybe Imperials and a couple other top option Mopars? Just like EFI, the early '80's Imperials had a MAF based TBI system, long before the trucks & 2.2/2.5's got it.
