It's cake.Use a regular 2 or 3 ton floor jack. Cut a 3/4" thick board about a foot square and place on the jack's pad. With the car on jack stands and the gas tank out, roll the jack with rear under the car and elevate carefully.
Use the drift or awl as suggested to align the two top bolts and tighten them to 100 lb/ft. Connect the trailing arms to the chassis
then remove the jack.
Here's a snap of the rear when I changed ratios, sitting on the board. Just size the board to support the cage and dif and no bigger.
