Where to place axle stands?

[waitey]

Hi I'm going to fit my coilovers soon but will have all 4 wheels off the ground, where's the safest place to put axle stands and leave them there for quite a long time?

Used the search and couldn't find anything suitable and the jacking up thread just said front two where the braces bolt on this photo:

Then two on the rear beam, are these the best for suspension changes?

The rear axle I wouldn't use as you'll need to drop it to get springs/shocks out... The two nice rectangular beams that run from front to back, I use those for axle stands, although not had all 4 off ground at same time though.
