Any "rigid" part of the chassis will work just fine. I have used:

In the front:
-The tow tow loops - work well, but need a tall jack to get a stand under the jack point.
-The upper joint of the LCA

In the rear:
-The square subchassis bar

I have had no issues with using any of these points. Just make sure you have the car centered on the jack as the car will shift a bit while you are raising it.
