My rear end went out I'n my 92 cummins .. I have a 2nd gen set up .. Will a ram van 3500 be the same reared as the ram 3500 with dana 70 ?

 

sometimes the van axles are wider measure backing plate to backing plate n go from there .

 

A van will have a chrysler rear in it probably not a dana, probably wouldn't last long

 

Dodge vans had an offset to the passenger side that the trucks didn't have.

Even if it is a Dana axle it would probably be a 30 spline 60 at best and is definitely weaker than what your truck came with.

I'd try to find a truck axle at all costs to save a bunch of headaches.
