1970 Dart tail stripe location?

Painted on? I did! I laid out my own, it's wider than the original.... I used 1/4 in tape on the edge of the quarter panel to be the starting point of the small outside strip then made the center 7 3/4 wide.... then added the other outside strip... I also ended the strip all the way down to cover the valance from the side... Hope this helps... if you want to go original specs don't do it like me.
