I have a Sterling 10.25" rear axle out of a 86 F350.
Full float axle, Drum brakes (need replacing), 3.55 gears. I think it is a Open diff, but I haven't pulled the cover yet. I pulled this from the parts truck I had for my 88 F250 $150.
Has 35 spline shafts, larger pinion than D60/D70 and 10.25" ring gear.
