#2- The 72 reinforcing screw was made because GM found out over time the metal strap under vent window was prone to separate or break resulting in the opening spreading wider at the bottom of the door glass by leaving it you'll be able to prevent this occurring but you also won't match passenger side. So you eliminate a issue by leaving but affect the visual aesthetic of both doors matching in appearance.

Your willingness to come onto the forum and answer these kind of questions is why I keep buying parts from you.
Not many other sellers take the time to do that....I'm sure that I'm not the only one who appreciates it...
