My rear sway bar brackets are bad and as a result the car is handling like crap. I replaced the front with a rear sway bar "kit" but cant find anything like it for the rear sway bar. Just the endlinks. Does anyone know the part number of the rear sway bar or aware of a "kit"?

I think I saw a GMPP kit with front and rear sway bars and lower control arms but cant find it.

Thanks
