I got my replacement rear end and axles in today. I did the whole swap in under 3 hours by myself and in the rain! Thanks to DeliveryValve for his detailed "rear end write up"! That little Harbor Freight stub wrench was just the ticket. It made the job very easy.
I used his instructions and modified them. I removed the rear end and axles as one unit and installed the new rear end and axles as one unit. It was surprisingly easy. Just a lot of getting up, moving around and getting back up to move around (over and over). I never removed the tires or the brake calipers. It came right out and went right in.
The hardest part of the whole deal was getting the drive shaft hooked back up. Also, I have a bit of a shudder around 30MPH. So, I need to try the drive shaft on a different hole.
After getting the old rear end and axles out of the car.... I found out that my SEVERE clunking problem was just worn out AutoZone axles that the PO installed 20,000 miles ago. They were completely worn out. Holding one end and twisting the other, there is 1/4" of play on both of them. The old rear end turned out to be OK.
So, now I have a back up!
Also... Many thanks to daw_two for the parts! Top notch! My car is tight as new again (for a while).
