rear sway bar recommendations

Because 14" wheels are drying up, (thanks Wheel Vintiques) I have a set of five 14x5.5" small bolt pattern wheels. I'm just gonna run 215 70 14s all around.
My 65 Barracuda still has old bias-ply on 13" rims on it, but years ago got 4 chrome reverse 14" SBP from the wheel guy when I still lived in Indy. And he brought them to me, no shipping, as he was was coming to town for some reason. I had them blasted & black powder coated & have Falken tires on them.
It's been sitting for years & tires are probably past date now, but around town they'll be fine.
I picked that particular Falken tire size because they're very close to 13" tires in height, so speedo will still be close.
