...and they're much heavier. There has been some argument as to exactly how much heavier, and I don't know the exact amount, but I do know I could easily pick the 7.5 I took out of my car up and carry it around the yard, but I could hardly lift the 8.8 (much less carry it about)

You must have been a a bit "off" that day...

A guy weighed a 7.5" and 8.8" here. Here is another 7.5/8.8 comparison. Visteon, the manufactures of the 7.5" and 8.8" axles, have their own data here.
Summary:

"Narrow" LSD 8.8 w/o axles, brakes, brake lines, mooseballs, pinion snubber, fluid - 116 lbs
Open 7.5 in same condition as above - 103 lbs

Open Fox width 7.5, with axles, drum brakes - 170 lbs
LSD SN95 width 8.8, with axles, disc brakes - 203 lbs (215 w/quad brackets)
99+ 7.5 (w/mooseballs?)
99+ 8.8 w/o mooseballs - 16 lb difference

Unknown 7.5 w/o axles, fluid, brakes - 100 lbs
Unknown 8.8 w/o axles, fluid, brakes - 130 lbs (120 w/o mooseballs)

Visteon 7.5 - 129 lbs
Visteon 8.8 - 146 lbs

It seems the difference is around 10-30 lbs, not 80.

Edited to change grammar, add summary

Must've been. Or "on" the day I lifted the 7.5" :hick: I remember that 8.8" being heavy. Of course the 8.8 was complete (disc brakes, axles, LSD, etc), while IIRC I had the axles out of the 7.5...

*EDIT* I've found a pic of the 7.5 in "as removed" condition, in fact, taken only moments after the removal. Axles and drums were off, but mooseballs, shocks, sway bar, and backing plates/brake hardware were still on.
