Don't have pictures but maybe you can visualize.A J-bar is a bar that is shaped like a J with heim joints at each end,the top of the J attaches to a verticle bar or tube that is normally located ahead of the rear axel on the left side of the car.This tube has holes or an adjustable slide so that the J-bar can be adjusted up and down.The curved end of the J normally attaches to a plate that is bolted to the front of the rear axel at the pinion.This plate has holes so that you can adjust the J-bar up or down to control roll.
A lift bar is a bar or a triangulated arm that usually attaches to the rear axel housing normally just to the right of the center section and goes forward parallel to the drive shaft about 32 to 38 inches where it attaches to a bracket usually with a shock absorber.Its job is to transfer weight to the rear axel.
Hope this helps

Lift arm

J-bar


A Lift arm reacts torque applied by the rearend. A J-bar locates the rearend laterally. Two totally different animals.

They are completly different....a J-bar(type of panhard bar) hold the rear and from side to side, and controls the roll center. A lift bar lifts up on the frame when you get on the gas, thus pushing down on the rear end. In place of a lift bar you can run a pullbar. You need a panhard bar (J-bar) and either a liftbar or a pullbar.
