Tommy,

Here are some other pictures of that vent from behind, in case you try to have a parts counter match it up. I agree with Steve that they are probably 70-80s GM rear AC vents. These pictures are from a spare I have and a broken one. There are no part numbers on them, only a casting number of 269 on the black housing. Note that the chrome vent piece slips right out of the housing. Just remove the screws, spread the black housing a tad and out it comes. The wheel just rotates a plastic bar that pivots the vent wings open or closed.

I do not see any damage on your vent, so I would assume that there may just be an obstruction behind it. Remove the two screws and gently remove the vent to check for an obstruction. Bluebird trimmed these vents to fit as needed. Note that my broken one had the side rails cut off to make it narrower to fit on the front living area light covers. On my dash vents in front of the passenger, the back of the vents were cut off for more air flow as BB had constructed an inner a/c delivery box behind them. There was not very much depth behind them, so it could be possible that your black wing vents are just hitting the back of the air delivery vent and unable to move easily, if BB made a delivery a/c box for yours also. If so, just pop the two screws, close the vent and replace.
