As a whole door, and keeping within the same body style (2drHT I presume?) the '67-72 doors will interchange. The differences will the interior lock knob location (and it's related internal linkage pieces), exterior moldings, door panel pattern, and in the case of the '67, window crank, arm rest base, and pad. Now, if you start adding convertible models to the mix, there are a few other items including the door glass, and vent frames (vent glass is the same). Keep in mind that there is both clear and tinted glass all those years if you're looking to match what you have. If your car is a 4dr, the interchange is '67-76 with the same notes as the 2drHT plus a few other minor items.
