Size of the center casting after you've worked on several of them. However, Dana/Spicer cast a number right into a web of the casting on the outside that can be read if the axle is somewhat clean.
Dana 44's are usually used as rear axles in 1/2 tons and as front axles in 1/2 & 3/4 ton 4x4's.
Dana 60's are usually used as rear axles in 3/4 tons and as front axles in 1 ton 4x4's.
Dana 70's are usually used as rear axles in 1 ton trucks.
As with all rules, there are a few exceptions...
If the axle is still in a truck, the axle code on the VIN tag will tell you what axle the truck was built with.

my axle code is 08, which I looked up as meaning I have a 3.5 rear end (if nobody changed it over the years). Is a Dana 44 a 3.5 rear end? Or are Dana 44's available in different ratios?

No, actually it means 3.50 ratio Ford 9" without trac-loc. Should be 28 spline axleshafts. For 67-79 1/2 ton trucks, the 9" is far more common than the Dana 44.
The previous post was an answer to which Dana axles were used in which trucks. Dana 44, 60, and 70 axles all have a cover on the back.
