1966 New Yorker body width

Hello I am a new member, and have just purchased a 1966 New Yorker 2Dr.
600 miles west in Denver Co. And am planning to haul it home this weekend
in an enclosed trailer 28ft.X 8.5ft. with (and here is the catch) fender wells
inside of the trailer 80in. apart that stand 14in. above the floor.
The specs that I find for the car all say 79.5in. width
But I am not sure if that is body width, or rear view mirror width.
Any help with the true width measurement of the lower body line would be greatly appreciated.
And may save me a trip to the lumber yard for 300 board feet of 2X12s.
Cheers radialwrench
