I've long wondered if the '72 park/turn signal lights can be directly swapped in place of the '70-'71 units. Until I try it (don't have the parts) I'm not sure if the resulting '70-'71 grille with '72 park/turn lights would look goofy or cool.
Oh yeah, and:
Yeah, they did. Just not in North America.
Here's a '79 Dart in Brazil.
Here's another one, and
here's a '77, here's a
'79 Magnum (fancy Dart 2-door), here's a
'79 LeBaron (fancy Dart 4-door), here's an
'81 LeBaron (final-year fancy Dart 4-door -- looks like a real nice one, with 318/stick)
