If you want to lift both rears up, put a block of wood between
the floor jack pad and the rear diff protector which is a nice flat
plate. Once you have your jackstands in place, the front can be
lifted by placing a block of wood between the floor jack pad and
the front crossmember. It is just behind the oil pan and has 2
bolts in it. If you use soft wood, the bolt heads just indent the wood and you have a wider contact patch. Place your jackstands
at the front factory jack points and your up on all four. Be careful
to not bend your pinch-welds at the jack points. If your jackstands will not span the seam, place a small block of wood just inboard of the seam to rest the car on.
