Thanks Bones, the info is a little hard to find but from what I have found so far the older (like mine) F250 and F350 SRW have the same frame, axle, brakes, drivetrain, shocks, engine, trans, coolers, radiators, and even rear springs. The only difference I have found is the standard overload spring and a lift block on the rear of the F350 SRW which could also be ordered in the towing package on the F250 making them exactly the same truck. It also looks like the base axle housing in the F350 DRW was the same, the 10.50 Sterling. The axle itself is rated for 9750 lbs and the GAWR is de-rated depending on what rear springs and tires the trucks came with.
