Is there a difference between a 1941 Ford business coupe headliner and a 1941 Mercury business coupe headliner? I have the 41 Mercury and it has 5 bows, all the pre made headliners for a business coupe I can find is for the 41 Ford with 4 bows. They say the regular coupe has 5 bows. I don't know if they will work on my car. I know my car is a true business coupe because my grandfather bought the car new.
