Installing this or any rear tie bar is not an easy task. You must put the rear of the car on jackstands, remove the wheels, and the two bolts at the ends of the suspension control arms. What's worse is getting these bolts back in with the new tie bar; because of the force of the springs, the control arm becomes misaligned with respect to the holes in the chassis, making it impossible to insert the bolts. Here's how I solved this problem: First, use a jack directly under the end of the control arm, where you're inserting the bolt. This should allow you to get the bolt through the tie bar and the front of the chassis, and into the control arm. Now the control arm is twisted so it doesn't line up with the rear holes. So remove the jack, and place it under the control arm again, but under the point where the spring/shock attaches. Jack it up several inches, until you're able to (barely) push the bolt all the way through and thread it into the welded-on nut on the other side. Be careful here since that spring holds a lot of energy and can seriously hurt you if it breaks free of the jack.
