Not worth the money for a jeep guy.  But if you have a B body and want an axle that bolts right in, it's well worth it.
The last one was for under $200 shipped.  It needs shafts, a carrier and gears, brakes but really, all that stuff would robably be changed anyway.  Look at what people pay for a TJ D44...
The Mopar D60 was one of those axles that would be a decent swap if you could ever find one, back in the day.
