Rear Sway Bar

[lsnova]

I am currently building a '71 Nova with a LS conversion. Putting Heidts Upper & Lower control arms, Heidts coil overs, 2' dropped spindles on the front. Already purchased 1.5" lowering Hotchkis springs for the rear. Looking for opinions on whether to add a rear sway bar, maybe one from Hotchkis? Have heard some people say leaf spring cars don't benefit much from a rear sway bar. Just doing all the fitting now, would rather add it now than later if I'm going to. Thanks for weighing in.
