Yes sir, They all used lag screws. They difference is in the door stamping and female hardware or lack of it.
As best I can tell someone has put some 68 parts in your 67 doors.
It has been done by others and will work as the body lines at the doors didn't change from year to year. Only change there is fast back and notch back.
Now if your car is a fast back and they used notch back glass and/or parts... that wont work. Anyway... the mounting bracket for the vent window has to be altered a little and someone probably already did that.
Here is what I would do. Use a service manual if needed to locate all the wing window hardware. If my guess is correct you will be poking a allen wrench through the hole in the upper door after the plastic plug is removed.
