I just added a couple of hooks off of a Suburban. (he wasn't using them)

See in this pic...

Just in front of the shock you see a bolt with a small bracket on it.
There is one on each side of the frame in front and in back.
That's where jate rings go. Of course you could have them welded anywhere you see prudent as well.
