67 Dart Door interchange?

Troub said

Thanks for the reply, my concern is the easy swap/mounting of any internals without mods?

All of the internals swap without issue.
You MAY have to redrill the pivot point hole for the door lock bellcrank, but the actual structure is the same for all 67-72 doors.
OR, if dead nuts originality is not an issue, I can send along the 68-up lock button hardware.
