Rockwell non steer rear alxe.

Housing alone: 145Lbs.
Chunk/diff section: 215Lbs. (with detroit, same as front section)
Hubs: 35Lbs each. (same as front)

My calcs could put together a rockwell rear for around 600-700Lbs with aftermarket brakes.

Sorry I don't have a weight for the front housing...was so excited to finally have parts I slapped it back together. I'll try and get a total weight at a later time for the steer rear.
