Scroll halfway down, you'll see a $70 set of shackles for an XJ (Jeep Cherokee). Super cheap way of lifting the rear of your vehicle. I'd bet you can get a reputable fab shop to do the same for $100.
Watch out for buginess, though. If you crank the t-bars and also lift the rear, you're going to end up with the same 'Present thyself' stance w/the azz end up in the air - great for rear clearance, but looks funny.
