I have a bare housing which I cannot positively identify.
If I use it, my intent is to narrow it, use Mopar ends and
internals and custom axles.

It is a "501" casting which I think is very similar to an
old Jeep Dana 60-2 rear housing, which is essentially a 60
with 44 tubes. Cast spring pads 40" apart, 6-bolt flanges.

Unless it is particularly rare for someone who would use it
as is, I would cut & weld it.

So really, my question is, would you use this housing in a
Hemi E-body with street tires, or should I get a housing
with 3 inch or 3 1/8 inch tubes ?
