69 Dart 1/4 marker lights

I have a pair from a '69 Belvedere or Fury. Are they the same across the entire vehicle lineup ?
I believe the darts are different.
nNo stufs on the rears… instead the have screw holes in the housing and brackets integrated into the 1/4 panel sheet metal .
The quarter extensions are to close to the outer skin to fit the acorn nuts and bracket like the fronts.
