Rear sway bar

I know I read in here somewhere about a 99 STS sway bar fitting my 99 Aurora. Does anyone know if this is true. If so, can I just order it and the brackets from the dealer and it will just bolt right up?

How about the front, is there a thicker one that bolts right up, or maybe a strut tower brace. I just seem to lean to much when taking curves. My 99 Catera sport was awesome on the curves.

RSM Racing has a strut tower brace...very expensive.

I looked into it. It doesnt work. So far the only strut reinforcement I have found is RSM.
