Suggestions on lifting the rear to change shackles

So, I need to swap out my rear spring shackles. Before I supported the car by the rear crash bar but the car is finished and I'm not using the rear cover to lift. Thinking maybe lift on the subframe connectors.... Ideas?

I've always lifted from the axle/diff and never had a problem. I recently pulled my rear springs and put blocks under the frame rails in front of the wheel wells (next to the spring perch) to support the car while I worked on the springs and shackles.
In my case I was working on a lift so had to deal with an un-even ground surface and only had room for a small floor jack.
Also, I have a set of wheel cribs that I use for blocking things like this. I like them better than jack stands.

That’s the same spot I used when I swapped my rear axle assembly.

Thanks guys. I know it is a basic question but I was just curious as to what others did.
Thanks!

Jack stand under each axle. Floor jack under the leaf spring being worked on.
Used this method to install lowering shackles on my street truck.

That wouldn't work. I need to drop the axel. The jack and stands in your scenario would lift them.

Lift the car from your differential, put Jack stands under the unibody frame section, keep the rear ended supported with your jack, unbolt the shackles and lower the rear end with your Jack while the body is still supported by the stands.
