68 dart "Go Wing" and Front Air Damn???

well i know they wern't stock but i have seen people put them on there. i just don't know which one is right?

My point exactly. If they weren't offered as an option from the factory, then there is no "right" one. It's up to you to decide whatever to put on your car.
Personally, I don't like the look of a wing on any of the Darts, either '60s or '70s - too 'ricer' for my taste. I much prefer the look of a trunk lid spoiler like Charlie Allen's '69 Dart 'Saddleback Dodge' funny car - see pic below of his car at OCIR in the very early '70s.
By the way, here's a link for a front aluminum air dam:
