67 to 69 DART CHANGEOVER

Weren't 69 marker lenses just rectangle reflectors until 70, when they added the bulbs?

True, but 69 fenders and quarters had recesses stamped into them. It's not just flat reflectors attached to a panel. They also fit into a "receptacle".

Is it NHRA? How picky are they? 1972 and up style could work. Would they even notice back-up lights and different tail light styles?
