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

Hello All,
What are the differences between the 65 Barracuda and 65 Valiant Lower Control Arms?
I'm looking at the Helwig #5906 Front Sway bar kit. It states it will fit a 64-67 Barracuda.
I want to put this on a 65 Valiant that currently has no sway bar installed.
Will the Hellwig bolt directly on? or do I have to replace the LCA's with ones that have a sway bar tab installed?
Thanks
