On the door post the axle code is B5
on the front differential tag is:
4 D9 VE8TA UG (last two are ?)
V6(or 5)1031 F-2
but both the V's look more like triangles, not letters.
Axle code 'B5' is a 4.10 limited slip, 5300 lb Ford rear axle, which is a 10.25" Sterling semi-float.
Having a semi-float rear axle, the truck would be a light-duty F250, so I would think the front axle would be the Dana 44HD rather than the Dana 50.
Someone may be able to translate the codes from the front axle to be certain, or you can look for the Bill of Materials number on the axle, which is a 6 or 7 digit number with no letters in it, usually stamped into the axletube not far from the differential housing, at least on straight axles anyways. You can take this BOM number and go to the Dana website for light duty truck axles www2.dana.com/expert, and look up what axle it is.
