Failed rear jackpoints, what else to use?

I always used the seam that runs down the side of the car. We all know the build quality of these cars when it comes to rust, so the rear jackpoints failed infront of the rear wheel well. What else should I use now? Is my car still safe to hoist up anywhere whether its my little jackstands or a garage's hoist?
 
^which is what the OP really should have been doing all along... and USE JACK STANDS!

^Or the center of the rear suspension.
