I replaced the bushings on the rear lower wishbones after installing the lifter, they fit correctly. Fixed rear end wobble due to worn 15 year old factory bushings. Removing the old bushings without a press was tedious, but possible. If you are unfamiliar with removing bushings, I suggest assembling a whole new lever, it's much easier and faster. But these whitelines that I know of are the only polygons made for 4runner.
