There is an 80's or early 90's Ford truck with duals I see frequently that has a straight axle under the front.
I presume it has disks on the front and maybe the rear also.
I've never measured it, but I'm sure its more like 72 inches or 76 inches across the outside of the tread.
I've not measured a '61 F350 but I would have guessed the distance across the the outside of the front tires to have been more than five feet. Could that measurement be a typo?
