Anyone have an original ignition coil with 1 D shaped terminal?

I know it's not a Charger but it's my 65 Valiant I'm trying to get started up. I need an ignition coil for it. I bought a new wiring harness from Year One and it was perfect down to every detail. But the ends for the coil connection had one with a D-shaped terminal. I didn't know if that was original because my original harness had been cut and spliced. I called M and H who makes the harnesses and they said the original off the assembly line would have had a coil with one D shaped stud I guess so as not to confuse - and +. But I can't find a coil with just one D shaped, I think it's the negative side. I even have the original coil number and see NOS ones aren't that way either. Does anyone have a coil like this? What coil can I use?
