I have a couple more numbers. Measured at the body reval line, it is 51"wide at the rear of the door frame.At the front of the door frame it is 43 1/2". The widest part of the body is 12" behind the door opening.I dont have any way of measureing that but it looks to be 1 1/2"on each side behind the door opening. That would make the body54" at its widest point.
