Anti-Sway Bar by PST installation

The 67-72 LCA's had the sway bar tabs (if so equipped) outboard of the shock bolts. So your bar is quite possibly correct for your chassis if you had the correct arms. Tabs can be fabricated and welded on wherever they need to be, but it's nice to bolt something together whenever possible.

Keep in mind that with your later calipers mounted forward they would likely foul the (early) sway bar near full lock. Swapping the spindles and calipers side-to-side to rear mount is a typical work around.
