67 Barracuda door

Will a 67 barracuda notchback door fit on a 69 fastback barracuda, I know the glass would have to be swapped anything else different?

Yes they are interchangeable but door locks knobs are positioned different and the mirror might be in a different position.

There are a bunch of suptle differences, but it will fit.

What about the "vent" on the bottom rear interior corner of the door?

Thanks for all your help! I will let the owner of the 69 what he can expect.

I think '67 and '68 have the lower door vent and the rearward edge interior lock. For 1969, the interior lock was moved forward for easier front seat access and the lower door vent was eliminated.

There are other differences.......
Vent window handle, screw through the door for the vent window frame.......
