I've seen photos of those vents before. Probably on another Frigikar system. Purely a guess but the purpose of the slot is to let a bit of cool air shoot straight across and maybe benefit the back seat a bit since the taller ducts direct it all to the roof high up toward the front of the car. Not sure they would do much for the frozen neck issue back seat passengers sometimes endured.
Can't tell with the mounting plate but the two screws appear to be in slots. Maybe that lets the operator rotate the ducts a small amount and direct the slot more toward the middle. Something I've been curious about is why the postwar aftermarket trunk ACs didn't have an option to place a large outlet in the middle like prewar Packard did. Place the returns on the edges. Seems that middle seat space would be empty most of the time and would allow better air flow to the front without freezing necks.
None of the aftermarkets ran ducts above the headliner where the edge outlets would be better and for those cars like some GM and Chrysler models that did have ducts and outlets above, they built their own units anyway.
