You'll need two people. put the jack stands on the frame (make sure they are very secure!)

Have one person pry like hell while the other one gets the bolt in the track bar. just try to get the axle to shift that little bit so you can get the bolt in (and watch out for brakelines, etc.)

You can drive it without a track bar, but very scary! I've watched it and I wouldn't want to be in the car when it starts floppin around.
