Another axle identification help

[jemarshall64]

Ok, got a pic of an axle, (there are a pair of them) but not sure if its a 60 or 70. Is there any good way to tell without popping the cover?

They came out of dodge motorhomes so leaning towards 70, but trying to make sure.

Read off and post the numbers off that tag that's hanging from one of the bolts holding the cover in place. Also, there's the bom number, which is stamped on one of the tubes, there should be a string of numbers stamped on the tubeing itself.

It will also be stamped into the diff housing a big '60' or '70' -- it will be under the dirt/grim.... That is where they always hide them :d
