Could somone tell me the width of a 1940 ford coupe door width and of the front door on a 4 door sedan?
I can't give you the measurement, but the 4 dr will bolt right on the coupe. Have to cut / grind a little off the top of the rear of the doors, weld them up and your good to go.
The approximate width of a 1940 Ford Coupe, and front Fordor Sedan door is 34-1/2 inches. The approximate width of a 1940 Ford Tudor Sedan, and Convertible door is 40-1/2 inches.
