Upadate: Today I did the final assembly for the rear end, and stored it away in a corner of the garage. Heare is a picture of it detailed and assembled.
I also pulled everything out from under the back half of the car. Gone is the gas tank, filler neck, shocks, and driveshaft. Next job will be to sand down (or up?) the underside, give it a coat of rust converter, and then prime it with Rust Encapsulator. I think I should also replace the gas tank also, I took pictures of the inside of the tank, what do you think?
