There was an excellent thread on this somewhere... try a search, it had a cool diagram.
But basically there are several places that are safe to jack:
1. K-member
2. Subframe "torque boxes", these are the big frame rail looking things on either side of the transmission
3. rear end pumpkin.
And there are several places safe to put stands:
1. A-arms... I like to put them in the spring perches.
2. subframe rails
3. right in front of the rear LCA mounts
4. under the sway bar mounts on the rear axle. I prefer the LCA mounts though.
I say generally I jack up the car by front subframe rails and the pumpkin, and put jackstands under the A-arms and the rear lower control arm mounts. It's better to jack it up by the k-member, it's just a stronger chunk of metal than the subframe rails, but I've seen too many incidents where a car will slide off the pad on the jack and destroy and oil pan. I just dont like doing it. It makes me nervous. Anyway, where you put the stands is going to depend on whether you need the suspension loaded or not.
Those are the front subframe rails on either side of my header collecters there. You can see mine are a little worn out from being used all the time to support the weight of the car.
