Approx weight of a complete 8.75?

The third member is right around 50 pounds. The axles I would guess 20 pounds each. The brake drum with backing plates and hardware another 20-25 pounds each. I would guess 150-160 dry, but awkward. Did i forget anything?

OEM axles would be around 20 lbs each! I just boxed up a pair of A-body 35 spline Moser axles with studs & bearings. They are the beefier 35 spline, but boxed up, it weighs right around 50 lbs!

Sure Grip or open rear would also make a noticeable difference.
