54 Cadillac doors
 

I have a 54 Cadillac 4 door sedan, fleetwood model, and Im wanting to know is there a difference in wheel between the 4 door and the 2 door? And also, does anyone know the length of the doors on a 2 door model? Im thinking of turning the 4 door into a 2 door, any help would be greatly appreciated, thanks.
