FWIW I installed a set of Cobb sway bar (F&R) on my 2005 LGT and have had lots of problems with the front. I used Kartboy links on the rear, but factory on the front. There were constant clunks from the front and in looking at it, it appeared that the bar was "walking" (wish I could watch it while driving!) Anyway I reasoned that solid links like the Kartboys would help stop the walking so I got a set for the front. BAD IDEA - DO NOT USE KARTBOY FRONT LINKS WITH COBB BARS! They self destructed in 2 weeks, tearing the rubber right out of the aluminum. At this point I have ordered a set of Cobb end links, but after reading this thread, I think I will double check their fitment when they arrive and add spacers if needed and also add some collars to keep the bars in place.
Remember - this is on a 2005 LGT, so beware.
