I suggest www.clubgp.com

It actually is the spring, not a swaybar.
I am not sure what other cars had them, but I know the early 90'* Lumina had the fiberglass spring also. I have seen many of them break and sag pretty bad in the back end
as far as i know the corvettes and first gen w-bodys were and still are the only cars to get them so: 90-94 lumina, 88-96 regal, 88-96 Grand Prix, and 88-97 Cutlass supreme.
they do break over time, some worse then others, mine just sags some, kinda annoys me but i'll live till i find a good one. w-body.com is an awesome resource for those first gens. neat implementation of IRS if you ask me.
