swaybar differences

i know most civilian caprices didnt come with sway bars from the factory, but are the ones with stock sway bars the same bars as the 9c1's?
also, if i was to put a swaybar on my car (didnt come with one stock) what modifications would need to be made to the lower control arms?

No most civvie front bars are not the same. Most of them that I have come across are hollow on civvie cars. The 9c1s are solid.

mine is a civie car and i bolted a 9c1 solid sway bar to it, no mods were done to the control arms, there should be 2 7/16" bolt holes on each control arm and the sway bar bolts it

sorry guys, my mistake. im talking about rear sway bars. i know that they were different in front, but if the caprice came with a factory rear sway bar would that be the same as the 9c1's?
are you talking about front or rear bars blownalcoholboy?

thanks guys
