Neither one of the ones in your picture should be used as a jack point. Many have gotten lucky and not dented the pan (at least visibly) if they used it once or twice. That doesn't mean you should use it.
Also Mango, what do you suggest for the front? When I get the whole front and rear off the ground I use 2x4s+ my jack to lift the front frame rail, then support it on the jack pads. If you jack up from the jack pads where do you put the stand?
