Weight of 7 1/4 vs 8 1/4 vs 8 3/4 vs Dana 60?

Well,I may not get to weigh a 7.25 this wknd., but I did weigh the
8.25 next to my 8.75. I had a sneaking suspicion this may be the
case, but I got news for you,it is every bit as heavy as the 8.75!!
With the same flared 10" drums(30#/pair),shoes,hrdw.,park cables
brake lines,lugnuts holding the drums on,etc. it is actually a tad more
than. The axle & backing plates alone are 149#, and that's 2.94
gears w/an open diff. so..... knowing that the welded banjo housings
are lite, the 8.75 is quite svelte for it's strength. It also is why you
see the same w/the heavy reinforcements welded to them in serious
applications.
I see lotsa numbers but not the ones we need?lol
