I don't know about diff tags - I never looked for one on mine, but my
Lineset indicated the 4.30 R&P - which was the tallest offered.  4.87,
5.57, and 6.17 were also offered.

I believe a Detroit NoSpin was available.  No limited slips.

It's a removable or "drop-out" third member.  Think "Big 9-inch".  Ring
gear is 11", and riveted in place.

Axle shafts are 1.5" diameter, 16-spline.

I don't think Rockwell built 'em, but I bet a lot of people don't know
that, and just assume "Rockwell" when they see the big drop-out axle.
