HELP: Will a 68 Dart hardtop door fit on a 69 Dart vert?

Yes the inside lock button is farther back on the 68, the vent window and frame is the same but the door glass is different in the conv. It drops down lower as it gets toward the back of the door. the glass is not that hard to swap. Roll both windows up and measure from the top of the door, you will see the difference.hope this helps...
