Hi all,
I also recently pick up a used differential on eBay( out of a 76 with 
65,000 miles) . After removing the back cover and checking backlash & 
eyeballing the rest this thing looks brand new. The gear oil was black 
but no metal sludge or filings. My original plan was to rebuild this 
unit before I installed it but because it's an unmolested & unabused 
example it's going in as is.
My questions are,
1)Anything else I should look for
2)I would like to wash the old gear oil out, what should I use
3)Has anyone used synthetic gear oil & what do you think
As always, thanks
