Differences between 65 Barracuda and 65 Valiant Lower Control Arms For Sway Bar Installation?

According to Summit for my 65 Cuda I would need #55917.
that's a tubular bar that's narrower for 18" wheel clearance on 67~72 cars (and doesn't work with factory LCA tabs).

it might work with an early body because it's narrower, but the mounts will be different. proceed at your own risk.
