There ya go
6 x $350 = $2100

Or just rebuild it and be done with it.

Uh, your grasp of math is a little off. I have 6 different 8 3/4's, for 6 different projects, all of which I would run without hesitation. Or, I could have one rear end that works. That's not the same thing. I didn't buy 6 8 3/4's to get one good one, I bought 6 good ones. Well, more than that actually because I was talking about my wrecking yard finds, but whatever.

That doesn't even get into the fact that the rear axle in my Duster is one of the "expensive" ones, I have a couple C body and truck 8 3/4's that I picked up for $160, complete drum-to-drum, axles, center sections, all of it. I had to buy the B-body 8 3/4 for my Duster from another car guy, not a yard, so it cost more.
