F-Superduty rear axle width?

[u2slow]

Anyone know the wheel-mounting-surface (WMS) width of the 10lug Dana 80?

Spring perch spacing would be helpful also.

Going out on a limb here, I would assume its the same width as a f350 cab n chassis frame, not the cab n bed frame width.

I've been assuming for a long time without a measurement!

I did find this '97 listing, suggesting it's about 2.6" wider than a F350 C&C.

I’m not near my truck at the moment, but it’s definitely different back there from a F350 C&C. I’d be inclined to believe the 2.6” width difference.
