What the heck is up with 8-3/4" rearends?

Heh... rebuilt center sections on ebay are around $950. Complete rebuilt rears are going for $2800. That's about the price of a new Dana S60

Tell me about it!!! I gave $2,200 for an A-body 8.75 in unknown condition with an open diff 3.23!!

Course there was a 72 Duster with a really good condition sharktooth grill and a twin scoop hood sitting on that rearend as well....
