Interesting. I have two extra 67 Barracuda doors and both have vents at the bottom. Also used to have a 67 parts car and its doors also had the vents. Plus, of course, my 67 Barracuda driver. So I figured they all had them.
Just when you think you know something as a fact after several decades, turns out that it may not be as universally true as you thought. :realcrazy:
