You didnt say if this is a stock gm bar or a aftermarket bar. I just installed a performanceonline front sway bar, had the truck prepped for the new bar, I drilled out the rivets, had the new stock mounting brackets installed. Guess what, aftermarket bar I got didnt use any of the oem mounts or holes. I installed with truck suspension under load. I did have to turn the tie rod outer adjustment clamps 90degrees so their bolts didnt hit the sway bar.

I did notice a good improvement in handling right away.
