All I can find for the standard line of Ford Galaxie cars are related to the basic 4-door and 2-door sedans. In other words, they are a general fit type headliner unless the fabricator tells you otherwise. It's possible that the 4-door sedan headliner can be cut down to fit the 2-door sedan. Count your number of bows before you call any headliner supplier. You will also have to specify what design of vinyl you want. Choices are the crater type, tier type, and perforated type vinyls plus the color desired. Most headliner fabricators use the same patterns. They always leave extra material on the edges to insure a fit. A person will also have to specify if you need extra material for sail panels or sun visors if applicable.
I do my own trimming but I purchase headliners since they are time consuming to sew all the panels and listings together so 120 to 150 bucks is worth it for me. I can't make them for that price so why bother. They likely all come from the same place so I can't recommend any that are better than any other. I'd look for stuff in this price range but would avoid anything a lot cheaper or more expensive.
