Rear shackles are about 2" ($50 at SLR). If you give the torsion bar adjusting bolts a few turns should get you up in the front (up to you how much but I wouldn't go too high without high angle a-arms).
A very inexpensive 2" lift. You may need an allignment after you do it.
I sure if you search, you will find more than enough info on this.
