Thanks for the great information here. The Packard 58 from Mouser was a perfect fit for the headlight connector on my ‘73 Dart. Headlights were intermittently going off at night which is not acceptable!
Note the burnt brown (formerly light green!) insulation on the original terminal. Very overheated. It _is_ 50 years old. Chrysler simply didn’t design them to last this long.
You guys saved me a lot of hunting and trial and error finding the right terminals.
