I posted a response similar to this in the buy/sell forum today and thought I'd go back and add the pics in a thread in the suspension forum for those who are researching this mod to help illustrate differences between the two swaybar endlinks
Below is a picture of the front sway bar endlink from a 22mm swaybar. The 22mm front sway bar is found on the 94-99 LS.
Below is a picture of the front sway bar endlink from a 24mm swaybar. The 24mm front sway bar is found on the 00-01 LS......94-01 GSR......97-01 ITR
Notice the difference in the design of the endlinks. The 94-99 LS front sway bar utilizes 4 rubber bushings versus the 00-01 LS/GSR/ITR front swaybar which uses a heim joint (more rigid) and only 2 rubber bushings. Less rubber bushings = less flex. And we all know that less play in the sway bar setup means the suspension will be more responsive.
