Alright, so it's clear that pickins are slim on sway bars at this point. Correct me if I'm wrong but it seems that Mantapart, with their glorious reputation

, seems to be the last bastion of sway bars for us. So my question is this. I have a 99 GLS with the sport suspension package. The car has 245k on it. To what degree to sway bars deteriorate and wear out? Since I am tearing apart the entire suspension, and I do mean entire, should I replace them, and if so, would the hassle of dealing with Mantapart be worth any benefits I would see over the sport suspension pieces I could get from GM?
