69 Dart side marker to light conversion

I have been told that 72 Duster marker lights a dimensionally similiar.. Though I'm not positive of that. Here's the thing, I was going to change my Dart to actual illuminated markers. Seeing as how there is fabrication involved, I say use whatever marker lights you like or think would look good on a Dart. Do some research on marker lights, not only from that era, but even later. When I was thinking of doing it, I had considered the marker lights from my 94 Beretta. I thought they would look cool. But as I said, in the end I decided to keep it the stock reflectors
