Mark - Just behind the front cross member is a round tube that runs side to side. Welded to it (on either side) is a square bracket. Put your jack stand on that point. You can also go ahead of the fr axle where the front frame rail splits into a Y, have never used that position as my stands aren't that tall. Its is easily visible with the wheels on.
all detailed in the owners handbook as well. Generally you want the stands as far outboard as possible, I wouldn't try to put them where the jack goes
as there isn't enough width to be safe.
