How much weight gain from adding a Dana and roll cage.

I just weighed my black friday purchase..... an aluminum 9" center, with a spool. 61.8 lbs, with half of the plastic shipping container. So, probably 59 lbs. (Frankly, more than I thought it would be.Thick aluminum casting, 10 bolt pinion support, billet 1350 yoke) Black Friday price saved about $600.
