Hi all, I need some help identifying a car based on a partial photo of it. The photo was taken on March 28, 1974, so the car must have been available to the public before then. I'm guessing it's a Chrysler based on the hubcap, but I'm having trouble finding a year/model with the same trim, trunk style, and door shape. If any background would help, this is part of a photo of former Texas governor Dolph Briscoe.
Thanks for reading
